Because this version is a 16-bit program, you do not need to have Win32s(R) installed on your computer. If you are using Microsoft Windows NT(R) 3.51, install the mini (browser only) or browser/mail version. This release includes Microsoft Windows 3.1 Virtual Machine (VM) for Java(TM). It supports the same feature set available in Sun JDK 1.02. - To run the browser only: - 4 MB, 386 processor required; 8 MB, 386 recommended - To run the browser and Java VM: - 8 MB, 486 required; 12 MB, 486 recommended - Microsoft Windows 3.1 or 3.11 or Microsoft Windows for Workgroups 3.1 or 3.11 - A VGA monitor or better - A mouse - A 9600 BPS modem or a LAN connection Note If you are running NT 3.51, the service pack 4 is needed. Otherwise, you will see instability in the VM. -------------------------------------- INSTALLING MICROSOFT INTERNET EXPLORER -------------------------------------- Installing from the Internet ---------------------------- To install Microsoft Internet Explorer from the Internet, carry out the following procedure. Important For the 40-bit version of Internet Explorer, the name of the download file is Dlful30f.exe. For the 128-bit version, you determine the file name at the time you download it. 1. Create a temporary directory on your computer. 2. Choose to download Microsoft Internet Explorer from the Internet, and save the download file to the temporary directory. 3. In File Manager, run the download file to extract the program files. 4. Read the instructions below for LAN installations and for installing with existing TCP/IP connections. 5. In File Manager, run Setup.exe. Setup installs files in the directory you specify. Note If you are upgrading to a newer version of Internet Explorer and choose to install the program in a different directory from your original version, please refer to the following section, "Upgrading over Earlier Versions," for further instructions. 6. Run Internet Explorer. Upgrading over Earlier Versions When upgrading to a newer version of Internet Explorer, you can choose to install the program into the same directory as your previous version or establish another directory. If you choose the former, your previous dialer settings and connection(s) will be preserved. However, if you choose the latter, you must do the following in order to use your pre-existing dialer settings and connection(s): 1. If you install to a new directory, but keep your existing program group, you must change the properties of any dialer program item(s) you previously created so that the Command Line and Working Directory settings point to the appropriate directories. (Note that the New Connections program item does not need to be modified.) You do this by clicking the dialer program item, choosing Properties from the File menu, and replacing all references to the existing directory with the name of new directory. For example, if you install an upgrade of Internet Explorer to a new directory named NEWEXPL, the following change would be required: Command Line: C:\IEXPLORE\iedial.exe C:\IEXPLORE\CON0000.CON Working Directory: C:\IEXPLORE Changes to: Command Line: C:\NEWEXPL\iedial.exe C:\NEWEXPL\CON0000.CON Working Directory: C:\NEWEXPL 2. Using File Manager, copy all files with the extension .con from the previous directory to the new created directory. 3. If during the upgrade you choose to use a new program group, just follow step 2 and copy the old dialer program items to the new program group. Repeat step 1 to change the Command Line and Working Directory settings. LAN Installations ----------------- If you already have access to the Internet through your LAN, you will be able to use Internet Explorer to browse the Internet. (If you are not sure whether you currently have access, consult your network administrator.) If you have access, your LAN administrator should provide you with the address of proxy servers that can be used. To install Internet Explorer, you need to do the following: - Make sure you have the TCP/IP protocol installed. - Run the installation in Custom mode, and make sure that the check box labaled TCP/IP Stack And Dialer is not selected. Proxy servers can also be used, provided they are CERN compliant. To enable use of a proxy server: 1. On the View menu, click Options. 2. On the Connection tab, select the check box under Proxy Server, and then click Settings. 3. In the Proxy Settings dialog box, type the address of your proxy server and change any other necessary settings. Running on a Remote Installation -------------------------------- If you will be running Internet Explorer on a diskless workstation: 1. Install Internet Explorer on the server. 2. Copy Iexplore.ini to the client Windows directory. If you will be sharing a remote installation from a client computer running Windows 3.1: 1. The following files must be in the client computer's Windows\System directory: Comctlie.dll Vscrpt16.dll Jscrpt16.dll Secur16.dll Security.dll Msapsp16.dll Msnssp.dll Signin16.hlp Msnath16.hlp and optionally the following RealAudio files: Ragui16.dll Ra16.dll Ract14_4.dll Ra3228_8.dll Pnloader.dll 2. The client computer must have OLE 2.03 or higher installed. Copying the OLE files will not properly update the system. 3. The file Iexplore.ini should be on the client computer. 4. The contents of the Iexplore.ini file should be modified to accommodate the desired location of favorites files, help files, cookies files, and other URLs that are specified here. Before Using the Mail Client ---------------------------- This software includes Internet Mail for Windows 3.1 and Windows NT 3.51. Internet Mail enables you to send and receive electronic mail using the Internet. In order to use Internet Mail, you need to have an e-mail account. If you did not use the Internet Connection Wizard to setup Internet Mail, you need to configure Internet Mail before using it. If it has not been configured, Internet Mail will ask you to enter the following information: - The names of the network servers that you use to send and receive your mail (the name of your POP3 and SMTP servers) - Your login name and password on the server from which you retrieve e-mail - Your e-mail address If you are not ready to enter this information, contact your system administrator or your Internet service provider for assistance. Installing a Modem ------------------ Before setting up, please make sure that your modem is turned on and properly connected. Setup will try to detect and configure your modem. If a modem is detected, but the exact type is unknown, select the modem manually from the list of supported modems. If a modem is not detected or you select the check box labeled Don't Detect My Modem, you can select the modem manually. However, the default maximum speed will be 9600 baud. Therefore, you should manually select a speed that matches your modem's capabilities in order to optimize the performance of the modem. Changing Initialization Settings for Modems ------------------------------------------- If you are using an older phone system or hardware, or if you are installing a "generic" modem, the existing initialization settings for the modem might not be sufficient. If you have problems with the modem, you may need to modify the Modems2.ini file in order to change the initialization settings. Use Notepad or another text editor to open the file, and then, in the modems section, locate the line for the modem, and modify the INIT line as needed. Using the Dialer ---------------- This release of Internet Explorer also supports dialer scripts. Note RAS is the only supported dial-up connection for Windows NT 3.51. IEscript.exe is located in the directory where you installed Internet Explorer. The program enables you to associate a script with a connection. To start the program, choose Run from the File menu in Program Manager. In order to use the dialer with a PBX that does not have a dial tone, you need to modify the DialString in the "Dial-In Configuration" section of the Shivappp.ini file in order to dial. For example, the X3 command would be inserted between the "AT" and "D" entries as follows: [Dial-In Configuration] DialString=ATX3D Note that adding the X3 command affects all locations and only functions properly with Hayes-compatible modems. To access an outside line, you might need to add a pause character (either a W or a comma) after the outside access number, so that there is a pause before the outside number is dialed. To specify this setting, click the My Locations tab, and then in the box labeled To Access An Outside Line, First Dial, type the outside line access number followed by a W or a comma. For example, if the number required to access an outside line is "9," you would type the following in the box: 9W - or - 9, If you Have Other Networking or Internet Dial-up Software on Your System (Multiple Winsock.dll's) If you've installed the Dialer program provided with Internet Explorer and there is other TCP dialer or networking software (Winsock.dll's) on your computer, Internet Explorer gives preference to those other versions of Winsock. This is a change in behavior from previous versions of Internet Explorer. If you do not need to use the other versions of Winsock.dll, you must remove or rename all files of that name EXCEPT for the one in the Internet Explorer installation directory, in order for the Dialer to work. If you do not want to remove or disable your other networking software, but want to use the Dialer, start the Dialer before starting the Internet Explorer browser in order to load the appropriate version of Winsock. In this case, to use the other software, you must close the Dialer, and then start the browser. Using Third-Party Telnet Helper Applications ---------------------------------------------- To configure Internet Explorer to use a Telnet helper application, open Iexplore.ini and locate the [Helpers] section. Remove the semicolon (;) from in front of the telnet= line, and type the path to the telnet application. For example: [helpers] telnet=c:\windows\telnet.exe %s Installation with Existing TCP/IP Connections and ISP Accounts -------------------------------------------------------------- Internet Explorer has been installed and tested with several of the most popular Internet access products available today. If it is configured properly, you should be able to use the TCP/IP protocol and dialer (via Winsock.dll) provided with these products to connect with your Internet service provider (ISP). It is not necessary to install the Dialer and TCP/IP stack that are provided with Internet Explorer. In general, all that is required is that you configure the PATH command in your Autoexec.bat file so that Internet Explorer can find the Winsock.dll file you are using to connect to the Internet. For example, if your Winsock.dll file is in the directory C:\Connect, add a line directly under your current PATH command that reads: PATH=%PATH%;C:\CONNECT If you have multiple Winsock.dll files, please make sure that the Winsock file you choose to use comes first in the PATH command or is located in the directory where your browser files reside. See also "If you Have Other Networking or Internet Dial-up Software on Your System (Multiple Winsock.dll's)" earlier in this document. Following are procedures for installing Microsoft Internet Explorer over some common Internet access products. Other packages available include FTP Software, Network TeleSystems, and shareware from Trumpet Software (http://www.trumpet.com.au/wsk/winsock.htm). Internet Chameleon 4.5 ---------------------- 1. Install Internet Explorer to the suggested default directory (C:\Iexplore). 2. Make sure that the Internet Chameleon directory is in your path. If it is not, add it to the PATH statement in your Autoexec.bat file, and then restart your computer. 3. Run the Internet Chameleon dialer program (from the Custom icon). 4. Select the line corresponding to your current Internet service provider, and make sure that the Dial On Demand command on the Setup menu has a check mark by it. This makes the dialer program run when Internet Explorer tries to connect to the Internet. 5. Start Internet Explorer by double-clicking the Internet Explorer icon in the Microsoft Internet Explorer group in Program Manager. If you have configured the Chameleon dialer to dial on demand, an Internet connection is made when you first enter an Internet address in Internet Explorer. If you have not configured the Chameleon dialer to dial on demand, you need to start that program before you start Internet Explorer. Netscape Navigator 1.2 Personal Edition --------------------------------------- 1. Install Internet Explorer to the directory that contains your Netscape Navigator files. For example, if you installed the Netscape browser in the default directory (C:\Netscape), place the Internet Explorer files in the same location. 2. Run Internet Explorer. Other Internet Dialer Packages ------------------------------ 1. Using the Custom setup option, install Internet Explorer to the suggested default directory without the TCP/IP stack and dialer. 2. Make sure that the Internet dialer directory is in your path. If it is not, add it to the PATH statement in your Autoexec.bat file, and then restart your computer. 3. Run your existing Internet dialer program. 4. Choose to enable dial on demand (if your dialer supports this option). This makes the dialer program run when Internet Explorer tries to connect to the Internet. 5. Start Internet Explorer by double-clicking the Internet Explorer icon in the Microsoft Internet Explorer group in Program Manager. If you have configured the dialer to dial on demand, an Internet connection is made when you first enter an Internet address in Internet Explorer. If you have not configured the dialer to dial on demand, you need to start that program before you start Internet Explorer. Making a Backup Copy of the Software ------------------------------------ 1. Make sure that you have three floppy disks (3.5" disks with 1.44 MB capacity). 2. After you have downloaded the software and have run the download file (see "Installing from the Internet" earlier in this file) your temporary directory contains all the files that you need to make disks. 3. Copy the file Iew31_4.cab on your disk number 4. 4. Copy the file Iew31_3.cab on your disk number 3. 5. Copy the file Iew31_2.cab on your disk number 2. 6. Copy the following files on your disk number 1. Files.inf Readme.txt Iew31_1.cab Setup.exe Install.lst License.txt Install.bin Setup.ini Changing the Default Installation Directory ------------------------------------------- Setup enables you to change the name of the installation directory for Microsoft Internet Explorer. The default directory name is C:\IExplore. If you choose to install Microsoft Internet Explorer in a different directory, please make sure the new directory name does not contain any special extended or DBCS (Double-Byte Character Set) characters. Only characters in the lower ASCII range can be used for the name of the installation directory. ------------ VM FOR JAVA ------------ This release includes Microsoft Windows 3.1 Virtual Machine (VM) for Java(TM)*. It supports the same feature set available in Sun JDK 1.02. At least 8 MB is required to run Java. Note If you are running NT 3.51, the service pack 4 is needed. Otherwise, you will see instability in the VM. How to Disable the VM for Java ------------------------------ To disable Java applets in Internet Explorer because of security or other concerns, carry out the following steps: 1. Click the View menu, and then click Options. 2. Click the Security tab. 3. Clear the Enable Java Programs checkbox. Settings for Java ------------------ The settings for VM for Java are in the JavaVM section in the Iexplore.ini file, which is located in the Windows directory. You can modify the following settings by using a text editor, such as Notepad, to open the file. ClassPath: Lists which directories to search for classes. If you want to run Java applets on your local computer, you can put all the class files into an uncompressed Zip file and add the full path of the Zip file to your ClassPath string. For example: ClassPath=c:\iedir\classes.zip;c:\myclass\myclass.zip DefaultOptions: The options for Java VM mx<number> Sets the maximum Java heap size. ms<number> Sets the minimum Java heap size. ss<number> Sets the C stack size of the VM. oss<number> Sets the Java stack size of the VM. verify Verifies all classes when read in. verifyremote Verifies classes reading in over the network (default). noverify Does not verify any class. Typically, you do not need to change the default options settings. However, if you have problems running large and complicated applets (which include many classes and need more heap space), try increasing the numbers for the ms and mx settings. By default, ms is set as 600KB and mx is set as 2048KB. You can increase the number of the ms option to 800KB or so; or, increase mx to 3096KB or so. However, ms should not be larger than mx. You can try this when you see an Out Of Memory exception on the browser status bar. *Java is a trademark of Sun Microsystems, Inc. Technical Support for VM ------------------------ VM for Java is supported through the Microsoft News Server. The following newsgroup is dedicated to the discussion of VM for Java and provides a great deal of support: news://msnews.microsoft.com/microsoft.public.java.win16.all Note For general discussion of Internet Explorer, use this newsgroup: news://msnews.microsoft.com/microsoft.public.internetexplorer.win3.1x To set up Internet Explorer to use this news server, follow these steps: 1. In Internet Explorer, click the View menu, and then click Options. 2. On the Programs tab, click the News button. 3. In the News Server Address box, type: MSNEWS.MICROSOFT.COM Known Issues with Java on Windows 3.1 ------------------------------------- Java is a 32-bit multithreaded technology that uses case-sensitive long file names and UNICODE. Windows 3.1 does not provide these services, which means they have to be emulated in the virtual machine. Further, Windows 3.1 machines typically have slower processors and less memory than Windows 95 or Windows NT, so fewer resources are available to applications. As a result, it is not possible to provide the same Java experience on Windows 3.1 as on Windows 95 or Windows NT. Two of the symptoms you will see when you use Internet Explorer with Java applets are as follows: -- OutOfMemory exception on browser status bar. This message indicates an out-of-system-memory error. The Java virtual machine allocates limited memory for Java run time. If the Java applet is too big, it will use all the memory available on Windows 3.1. -- Random GPFs. This may happen when your system runs out of USER or GDI resources. The USER and GDI resources are limited on Windows 3.1 and they are shared by all programs. You may see GPFs occur in different applications when this happens. -- For non-Latin1 versions of Windows, this release of Internet Explorer does not support loading Java applets in directories named with extended characters. It will be supported in the next release. --------------------- KNOWN ISSUES AND BUGS --------------------- * No inline video. * No Internet shortcuts. * You cannot open another instance of Internet Explorer by double-clicking an .htm file in File Manager or double-clicking the Internet Explorer icon in Program Manager. To open a new instance of Internet Explorer, choose New Window from the File menu. * If you have voice messages waiting on your phone line (rapid beeps), our Dialer fails to dial out on the line. This can be remedied (for Hayes- compatible modems only) if, in the file Modems2.ini, at the end of the line for the InitString setting, you set "blind dialing" by typing: S6=5 * Internet Explorer might have difficulty loading a very large number of newsgroups (>16000). If your news server has a large number of newsgroups, you should use a dedicated newsreader to browse the groups. * After upgrading to version 3.03, if you run an earlier version, you might get a dialog box stating "Could not :Load Entry Point in Security Protocol Module: Proxy_Basic=Proxy_basic_Load,basic.dll." Just click OK and continue or copy the Basic.dll from the 3.03 installation over the Basic.dll in the previous installation. * You might experience problems running some plug-ins. We are working with several vendors on these issues. * Pressing the TAB key does not select the Address bar as in previous versions. * If you are running Windows NT 3.51, the background of the Font Preview box (on the Font tab in the Internet Mail Options dialog box) will sometimes change colors. In some cases, this color may be very dark, making it impossible to see the font being previewed. It is, however, still possible to change the font. Restarting your computer a few times may solve the color problem.
