Please go through this post.

From the post:

1. Click Start -> All Programs -> Accessories -> Run In the Open textbox paste in the following line (see list of all .NET Framework version install, repair and unistall command lines here):

For silent repair on 32 bit computer with .Net Framework version 4.0.30319 use:

%windir%\Microsoft.NET\Framework\v4.0.30319\SetupCache\Client\setup.exe /repair /x86 /x64 /ia64 /parameterfolder Client /q /norestart

For silent repair on 64 bit computer with .Net Framework version 4.0.30319 use:

%windir%\Microsoft.NET\Framework64\v4.0.30319\SetupCache\Client\setup.exe /repair /x86 /x64 /ia64 /parameterfolder Client /q /norestart

2. Click OK to start the repair. 3. After, the repair ran for a few minutes, I restarted IIS 7.5, and things began to work correctly!
