I am glad you managed to fix your problem that "easily"! Visual Studio is well known to create a mess in the machines it is installed in. There is probably a way to use both of them without any conflict, I'd give a look on a VS tech support Forum. They should know it better.

I tried re-installing the libraries as well (DirectX, DotNet, VCredist) but to me it doesn't do the trick, CoD still doesn't launch.

Looks like even the slightest change in the machine is gonna prevent CoD from working. :mad:
