While learning ZyINDEX, Qubie version, I installed ZyINDEX from the ZyINDEX
Master Disk to my hard disk, experimented with ZyINDEX, and erased the ZyINDEX
program files from my hard disk to free up space. This worked fine until I
tried to install ZyINDEX for a third time. At this time, I received a message
to the effect that ZyINDEX could be installed only two times to a given
hard-disk system. I was further informed that I would be allowed to install
ZyINDEX one more time, although I should buy a regular version of ZyINDEX.
I was infuriated and decided to do something about it. First, I used PC
Magazine's ATTR.COM to check for any hidden files that ZyINDEX may have placed
on my hard disk. There was one, ZYLABQXZ.ZYX, in my root directory (The
audacity of those people still irritates me.). Then, I used ATTR.COM to
convert ZYLABQZX.ZYX from a hidden file to an unhidden file. Finally, I
deleted ZYLABQZX.ZYX from my disk. Subsequent installations of ZyINDEX onto my
hard disk have worked fine, and I have since created ZINSTALL.BAT to facilitate
this process.

For your information, PC Magazine's instructions for the use of ATTR.COM

ATTR (Attribute) Charles Petzold
Command No. 1
______________________________________________________
Purpose: ATTR.COM permits display and modification of
the archive, system, hidden, and read-only
file attributes.
Format: ATTR
or
ATTR *.*
or
ATTR [+A|-A] [+S|-S] [+H|-H] [+R|-R]
[d:][path]filename[.ext]
Remarks: Entering ATTR without any parameters, as in
the first format shown above, produces a help
display (essentially identical to the third
form above) that shows which file attributes
can be changed.
ATTR.COM permits the use of the global ? and
* characters (as in the second format above).
Entering ATTR filename displays a specific
file's attributes. For example,
ATTR IBMBIO.COM
returns the display
IBMBIO.COM Arc Sys Hid R-O
showing that the Archive, System, Hidden, and
Read-Only bits of the attribute byte are set
for this file.
When wildcards are used to list the
attributes of all the files in a directory,
subdirectory names are shown as Dir (between
the Arc and Sys in the example above).
Unlike the DOS DIR command, ATTR lists hidden
files, whether sought by specified filename
or through a *.* listing. However, ATTR does
not show Volume names or the dot and double-
dot entries in subdirectories.
The syntax for changing file attributes is
indicated in the third format above. After
typing ATTR (and a space) you simply precede
the file specification with a plus or minus
sign, followed by the letter A (Archive), S
(System), H (Hidden), or R (Read-Only). A
plus sign turns on the specified attribute; a
minus sign turns it off. More than one
attribute can be changed at once, and the
attribute-designating letters may be entered
in any order and in upper- or lowercase. No
space may be used between the plus or minus
and the letter that follows it, however.
Example: To convert the file 85TAX.WKS to hidden and
read-only, you would enter
ATTR +H +R 85TAX.WKS
Since DOS itself normally sets the Archive
bit, entering
ATTR 85TAX.WKS
would produce the display
85TAX.WKS Arc Hid R-O
Since the Hidden attribute has been set,
however, the DIR command will produce the
message, "File not found." And since the
Read-Only flag has also been set, a DEL
command will produce the message, "Access
denied."
Notes:
1. Requires DOS 2.0 or later.
