Check to see if .NET Framework 4.0 is properly installed with this tool:
If it is not installed properly, first try removing it through Control Panel, then use this cleanup tool:
Then empty your %temp% folder, disable your AV and anti-malware software and run the .NET Framework 4.0 standalone installer "as administrator".
