microsoft.net v4 won't install

Question

Hi,

I'm trying to install .net v4 and I continue to get errors.  I've tried many of the suggestions in the other threads, but nothing has worked (and in many cases I don't even have the directories I'm told to rename/delete).

Here's my most recent error log:

OS Version = 6.1.7600, Platform 2
OS Description = Windows 7 - x64 Home Premium Edition

Thanks!

Hi skovinsky,

We need logs to analyse your error.

Please use http://aka.ms/vscollect  to point to the collect.exe tool.

This will survive any changes to the download URL that may happen in the future (especially important given the Internet's long-term memory).

For how to use it, please refer to this blog:http://blogs.msdn.com/b/varungupta/archive/2009/10/26/instructions-to-collect-net-framework-4-and-visual-studio-2010-beta-setup-logs.aspx

Hi skovinsky,

I suggest you try the steps below:

Follow ALL these steps exactly:

Before trying to install .NET Framework 4.0, execute this command from an ELEVATED Command Prompt provided by the .NET Framework Team:

"This issue is likely caused by a bad ACL on assembly\tmp folder. After installing updates, the ACL propagates to installed assembly folders in both 4.0 & legacy GAC.  If those updates were installed by WU or another user, the propagated ACL will prevent install of the same assembly by the current user.

A work around would be to reset the ACL on GAC dirs.

for /F %D in ('dir %WINDIR%\assembly %WINDIR%\Microsoft.NET\assembly /s /b /a:d') do takeown /F %D && icacls %D /reset /T"

After running that command, follow these steps:

Please follow these instructions exactly:

1. Download a fresh copy of the standalone installer for .NET Framework 4.0:

2. Also, clear your %temp% directory and disable your AV software.

The %temp% directory is a reference to the Temp folder associated with the current user. To clear it, do the following:

Sign on to your system with the Administrator user account you will use to run the installer. Click the Start Orb and type %temp% in the search box. The search results will show the Temp folder you want. Click on the Temp folder to open it in Windows Explorer, then delete the entire contents.
