If you have ever uninstall and installing any application you have stumbled on this type of error (as happened to me, because I wanted to uninstall the framework 2.0 and reinstall it) are two solutions: the first severe, format your PC and the other, less drastic solution is to try.
After many adventures and reading many forums, I finally found the solution:

Otherwise you do a little summary:
- Go to C: \\ WINDOWS \\ WinSxS Delete the folder
- Policies
- Create a folder x86_policy.8.0.Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_x-ww_77c24773
- Copy from any folder with " VC80CRT" files and put them in the folder you just created in
- Delete% windir % \\ system32 DLL mscoree.dll
- Now you can launch the installation of the Framework
