If you do not use the Microsoft® Windows® Add/Remove programs feature and instead attempt to uninstall GAIN-supported applications by manually deleting files or directories, it is likely that your efforts will result in an incomplete removal of GAIN and/or your GAIN supported applications. In this case, please contact The Gator Corporation technical support at support@gator.com and they will be able to work with you to help you remove all GAIN-related components.





Q. Why isn't GAIN listed in the Add/Remove Programs window?

A. GAIN is designed to self uninstall when all GAIN supported applications have been uninstalled. You cannot uninstall GAIN directly, as it is correlated with other software products. You need to uninstall all GAIN supported applications in order to remove GAIN. "


*edit*
BTW: if all this doesn't work, in order to stop it from running when you boot up, you can do one of two things
1. start-->run
type "regedit"
click on Hkey_local_machine
scroll down
click on software
scroll down
click on Microsoft
scroll down
click on windows
scroll down
click on current version
scroll down
click on Run
once you have clicked on run, you will see programs in the right side of your window. these are all the executables that are starting when you start windows, look for gator (GAIN) and right click on it and press delete.

2. start-->Programs-->startup
make sure there are no unwanted icons in the startup folder. These also startup with windows.
