Microsoft .Net Framework 4 installation FAIL.. Help T_T

I'm trying to install VS 2010 for my programming class 

VS2010 installtion becomes stagnant on microsoft .net framework 4 installation 

.. so i googled and read forums and found that you need to uninstall the past versions of the .net framework... then

I tried manually downloading and installing the .net framework 4 but it still fails 

I read forums and tried the latest cleanup tool, but also failed...

I tried going to regedt32 and deleted the .net framework folder but also failed.

First, your research indicating that " found that you need to uninstall the past versions of the .net framework." is simply not true, and even dangerous in your case. You have Windows 7, which installed .NET 2.0, 3.0 and 3.5 plus service packs *as part of the OS installation*. If you attempted to remove these, you may have damaged Win 7. That may be causing your problems with .NET 4.0.

When you say you used "the latest cleanup tool", do you mean this one from Aaron Stebner?


You should have used it to remove v4.0 only.

In your situation, I would consider reinstalling Win 7 (assuming you really did attempt to remove earlier frameworks), then installing VS 2010.

Hi edmamerto,

Thank you for your post.
Appreciate for pvdg42’s suggestions. Please check his suggestion and check whether .NET Framework is installed correctly on your machine or not. Please download .NET Framework Verification Tool from the following link: http://blogs.msdn.com/b/astebner/archive/2008/10/13/8999004.aspx

Based on the error message, .NET Framework installation  was blocked when it tried to upgrade Windows6.1-KB958488-v6001-x86.msu via Windows Update with the error code "0x00000424".

Wusa.exe is Windows Update Stand-alone Installer in Windows Vista and in Windows Server 2008. So your problem could be caused by Windows Update.
For more information of Wusa.exe, see: http://support.microsoft.com/kb/934307

Please make sure that Windows Update has been turned on. If not, please turn on it, install  the latest updates from the Windows Update Site and try to reinstall .Net Framework 4.0 again.

If the problem still exists, you could try the following steps for further troubleshooting.

- Try to clean your "%temp%" folder (Start Menu >> Run >> Type "%temp%")
- Install VS2010
  (The installer must be run with administrator privileges - Right-click the installer >> "Run as Administrator")
- Collect the logs from "%temp%" folder
