There will be some new posts about some typical Microsoft Windows situations. Where you think the solution should be simple, but it turns out it’s almost impossible.

Installing .NET Framework 4.5.2 on Windows 7

This should be simple, the latest Framework will show up on Windows Update for installation, but this gives an error:

0x80070643

Microsoft offers some solutions for this here. Luckily none of them works.
If you try to install .NET Framework with the offline installer you get a strange error:

Returning IDOK. INSTALLMESSAGE_ERROR [Overlapped I/O operation is in progress. ]

After trying so many things I wanted to give up. Than I found a small message on the Microsoft website from a guy named: RURajesh Upadhayay:

The fix of this issue is to rename c:\program data\microsoft\crypto\RSA\S-1-5-18 and try re-installation of .net again.

This was the solution found after many hours waisted…
