I just tried to install the .Net Framework 4 on my Windows 7 64 bit system. The installation did not succeed - HRESULT 0xC80003F3

From the log file:

Here is what I did and it fixed it - Thanks to Mary.

Create a batch file with the following and run it from a command prompt.

Start File Below

regsvr32 MSXML3.dll /s
net stop wuauserv
cd /d %windir%\SoftwareDistribution
rd /s /q DataStore
net start wuauserv
regsvr32 softpub.dll
regsvr32 mssip32.dll

End File Above

Go to services and stop the Windows Update service
Go to the Windows directory (default is c:\Windows) and rename the "SoftwareDistribution" folder to "SoftwareDistribution.old"
Go to services and start the Windows Update service
