How to Install .NET Framework 4 on Windows 7 Bootcamp I am trying to install the Microsoft .Net Framework 4 on a Windows 7 bootcamp partition on my MacBook Pro. It always fails. I have tried installing it via the web platform installer and also the standalone download, but neither works.

This is the error message from the standalone .Net Framework Installer log:

Exe (C:\c6966332def2afc3e143c2e5079951\Windows6.1-KB958488-v6001-x64.msu) failed with 0xc8000222 - (null).
Final Result: Installation failed with error code: (0xC8000222) (Elapsed time: 0 00:01:02).


Does anyone know how to get this to work?
Well, I figured it out. I left out in my question that I was using VMware to access my bootcamp partition, where it didn't work. When I rebooted into "pure" bootcamped windows 7 the install went perfectly.
