Windows Installer Error - Fix

#1
Many people have reported getting "Windows Installer Not Responding" errors when trying to install a wide variety of programs.

The bug (and the initial fixes) was reported here, among many places. Then a few hours later, Chris Holmes (who found the original bug) made this second discovery; Microsoft has now acknowledged the problem and provided the solution through the Action Center.

Follow the directions on the screenshot or go via regedit and delete the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions.

Posts on TechNet and other reliable forums all report of success installing everything from Adobe, Java and even games that had failed to load previously.

A confirmation from Live Search - Beta QnA:

I am part of the CEIP team at Microsoft and wanted to share how to fix the issue and share more information.

Description:
New machines installing Windows 7 Beta will not experience this problem. An issue related to the Customer Experience Improvement Program (CEIP also known as SQM) client in the Windows 7 Beta is causing crashes of Explorer, MSI-based installers and other applications. In order to resolve the issue, impacted customers need to run the following script from an elevated command prompt. This script will stop crashes related to CEIP.

Background:
Microsoft deployed a configuration change which exposed this problem. The script provided below removes those changes (registry keys) to prevent further CEIP related crashes.

Detailed instructions:
1. Select and copy the following to your clipboard:
reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions /va /f
2. Click on \"Start\", then \"All Programs\", then \"Accessories\"
Right click on \"Command Prompt\", then click on \"Run as administrator\"
In the UAC prompt, verify that the program’s name is \"Windows Command Processor\" and then click \"Yes\"
Right click on the \"Administrator: Command Prompt\" window’s black area, then select \"Paste\"
Press \"Enter\", you should see “The operation completed successfullyâ€Â￾.
If you see “ERROR: Access is deniedâ€Â￾, please make sure you followed Step 3.
Close the \"Administrator: Command Prompt window\"
Thank you for using Windows7 BETA!
