Windows NT/2000
If the installation of the new product will not run after uninstalling the previous version, delete all the files in the Winnt\Temp, and the \Temp directory (be aware that many people store "working" files in here so it is best to check with the user to see if there is anything required contained here). Try running the installation once again after the files have been deleted. If the install still will not proceed, continue on to the instructions below.
The following instructions involve making modifications to the registry of the machine. Please make sure all necessary files that might be stored locally on the hard drive have been backed up, and that you have a current emergency repair disk for the machine that you are working on.
Begin by installing the Microsoft Windows Installer Cleanup Utility for Windows NT/2000. Save the file to the local hard disk and install by double clicking on the saved file. To run the Cleanup Utility, find the entry that was added to the Programs menu and run the only menu item that is associated with it. This program has nothing to do with the cleanup of the Network Associates product, it is only cleaning the remnants of the Windows Installer.
See below in the Windows 9x section for registry keys that should be deleted if they still exist. Most of the keys found below will pertain only to Windows 9x machines but similar occurences can be found under NT machines and should be removed.

Close all programs, and press CTRL-ALT-DEL, select everything in the list one by one with the exception of Explorer and Systray, and select 'End Task.' After all the tasks have been ended, try running the installation again. If the install still will not proceed, continue on to the instructions below.
