Ati catalyst install manager for windows 7 sp1 64 bit

First time I have heard of this on W7 it's usually just a .Net Framework problem remove the latest .Net framework using add/remove programs in the control panel and use Driver sweeper to remove Amd graphics.Reinstall the framework through windows update then reinstall catalyst that should do it.

reinstall with the newest version.

No need to reinstall .NET. Just install the newest AMD/ATI video drivers.

I have issues installing Catalyst as well. I have an AMD chipset and Graphics card and I can't install drivers for either because I can't install Catalyst... Such a stupid idea from ATI. I have dot net 4 framework and my Win 7 64 has all windows updates installed. Catalyst stalls as soon as I hit the "install" button. No error codes or anything - windows just tells me that the install failed. Any ideas on how to proceed would be much appreciated. Thanks!

Try uninstalling the ATI driver using ccleaner to get rid of any remnents of it, then reinstall the ATI drivers.

I installed ENU x64 and Catalyst installed

Make sure your Windows update is configured correctly... so that the correct .net framework is installed.. but this probably Isn't the case. Make sure your montherboard/chipset drivers are up to date or you might encounter strange errors like that. The most likely cause is that you have to uninstall and then reinstall your AMD drivers.
