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 ! 
Omega drivers has released their modified Drivers of the newest Official ATI Catalyst Drivers. Radeon Omega Catalyst Drivers will provide gamers with an alternate set of drivers, ones that have more options and features than the original sets. The drivers contain optimizations, extra features, more supported resolutions and internal tweaks that can give you the edge in a gaming environment over normal drivers, which are quite often tailored for synthetic benchmarks. The best part is that they work with ANY RADEON VIDEO CARD built/powered by ATI, including all Mobility chipsets (M6 and up).
The Omega Drivers are compatible with all ATI Radeon cards: (it doesn’t matter if they are DDR, SDR, PCI, PCI-E, AGP, Mobile, Retail, OEM or 3rd Party)
