Default Trying to Upgrade From Windows 7 to 8 - 07-24-2013, 01:02 | posts: 1

Hi all,

I'm having a very frustrating problem when trying to upgrade my Windows 7 to Windows 8 Pro. I reach the point where the setup checks for "compatibility", only to receive an error message:

"An error prevented a required compliance check from completing. Cancel the installation and try upgrading again.

Installing Windows will affect these devices or applications:

ATI CATALYST Install Manager * "

This is what I did (in order) to try to remove it completely:
- Control Panel > Programs and Features > Uninstall ATI Catalyst Install Manager
- Ran the AMD Uninstall Utility
- Ran Driver Sweeper
- Ran CCleaner
- Restarted PC, tested, still got the same message...
- Looked for any folders with "AMD" or "ATI" and deleted them
- Deleted registry key folders with "AMD" or "ATI"
- Ran AMD Uninstall Utility
- Restarted PC, tested, still got the same message...
- Reinstalled AMD Catalyst Drivers/Install Manager
- Re-uninstalled it from the Control Panel, went through first 4 steps again

In my current state, the AMD Catalyst Install Manager has been removed (or so I think), but the Windows 8 setup still stops me saying that I must uninstall it to move on. I have also tried to use Revo Uninstaller, but the Catalyst Install Manager didn't even show up in the list of installed programs to begin with :/

Any help would be appreciated, thank you!
Chris

would be better to simply create a new partition on your hard drive if you only have one hd and install windows 8 to that so you can still keep windows 7 and go back to windows 7.

Try removing the device in Device Manager.

And check manually for any other left overs, regedit, etc.
