If you are the sort of person who doesn’t mind installing beta graphic drivers just so you can gain that extra 1% of performance, you have probably noticed that all the AMD Catalyst Beta drivers force install .NET 4.5 framework because someone at AMD didn’t do his job properly. My system has .NET 4.5 Framework properly installed, yet AMD Catalyst installer says “Current version not installed” and installs it over again. What this does is that it borks up your existing installation, so Windows Update will have to re-download all the security updates again which take ages to complete even on my main system which is no snail. It’s stupid and the one responsible for this moronic issue should be smacked in the face.
How to get around this problem?
Download the installer and run it as usual. Click Install and wait for the package to extract its files. When AMD Catalyst Install Manager appears, click Cancel and exit it. Now go to where the package extracted its files (for example: “C:\AMD\AMD_Catalyst_13.8_Beta2″).
Now open the folder where files were extracted and look for a folder “DotNet45″ inside “C:\AMD\AMD_Catalyst_13.8_Beta2\Packages\Apps”. Delete the entire “DotNet45″ folder. Now go back to main folder and run setup.exe again. This time, AMD Catalyst Install manager won’t even list .NET 4.5 Framework anymore.
This of course doesn’t mean you can use it without the framework, you still need to install it (once), but not every single freaking time you install new BETA drivers.
