To check for new Registry First Aid versions press the "Help" button, then click on the menu item Check website for new version. See a screenshot.
Registry First Aid performs version checks multiple servers to be sure users have the very latest version. The program will connect to the home website locations and get information about the latest version. If a new version is detected then the user will be prompted to open the web page to read more about the latest version and how to download the upgrade. These updates are usually free, unless there is a major version upgrade (i.e. from 3.x to 4.x), in which case this will be clearly explained.
No private information will be sent out. The program retrieves only the latest available program version number from the home website locations.
