With Catalyst 12.9 and newer, the CCC/Vision Control Panel will not work unless (at least) .NET Framework v4.0 from Microsoft is installed.
I am hoping this information will help:
This operating system ships with .NET Framework 4.5 already. You are good to go.
Vista and Windows 7
The .NET Framework 4.5 is a complete update, and will uninstall any previous .NET v4.x installs prior to installing itself. You can download version 4.5 here: http://www.microsoft.com/net.
It is not compatible with WindowsXP.
You need this version: http://www.microsoft.com/en-us/download/details.aspx?id=17851 , and then update it to this version: http://www.microsoft.com/en-us/download/details.aspx?id=29054
The second download link is the v4.0.3 update to v4.0, and is the last version that is compatible with WindowsXP.
