Answer 1

First, you did not uninstall .NET Framework 3.5 in Windows 7. .NET Framework 3.5 comes as part of Windows 7 and CANNOT be removed by a user.

Further, 3.5 has nothing to do with your .NET Framework 4.0 installation issue. The two versions are separate entities.

If the installer ran, there will be a log. Provide as follows:

After you run Collect.exe, you'll find vslogs.cab in your %temp% directory. Please upload vslogs.cab to a public site, like SkyDrive, and post the link here.
