Came across “cannot read from aticcc.msi” error (the 1316 cannot continue error thingy) while trying to uninstall ATI drivers ? Here’s a solution to get it uninstalled for good. [ Error : 1316 ]

Firstly, Get the Windows Installer CleanUp Utility from microsoft.com

Microsoft has updated the Windows Installer CleanUp Utility. With the Windows Installer CleanUp Utility, you can remove a program’s Windows Installer configuration information. You may want to remove the Windows Installer configuration information for your program if you experience installation (Setup) problems. For example, you may have to remove a program’s Windows Installer configuration information if you have installation problems when you try to add (or remove) a component of your program that was not included when you first installed your program.

Install it, run the Windows installer CleanUp Utility, delete all entries relatied to ATI, CCC, Catalyst etc., restart Windows and reinstall the new Catalyst drivers. And Voila !
