HRESULT 0xc8000222 when trying to install any version of .netFramework

This will occur mostly on Windows 7, never happened on Windows 8: 'Installation Did Not Succeed' .NET Framework has not been installed because: HRESULT 0xc8000222

There is a common problem with windows update and the .netframework. We'll have to clean the SoftwareDistribution folder before we proceed.

Click Start and Run:

cmd

This will open the well known Command Prompt, then type:

net stop WuAuServ

This will stop the Windows Update service. Make sure you're the admin.
Click Start and Run again, this time type %windir% and press Enter.
Look for the SoftwareDistribution folder and rename it to SwDist.old.
Now go back to the Command Prompt and start the Windows Update.

net start WuAuServ

That was it. Re-run the netFramework and it should work.
