Re register the .NET framework with:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe –i

Version will be replaced with that you have installed on the computer.

Alternatively you can do a silent repair using:

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

Try:

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

Will be for 64bit version as the previous one i gave was for 32bit installation.
