Windows 7 Installer hotfix

Microsoft released several new hotfixes for Windows 7. Among those there is a hotfix for the Installer that apparently seems to crash a lot while installing or updating certain applications.

Microsoft’s official statement:

“Microsoft deployed a configuration change which exposed this (installer) problem. 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 and removes those changes (registry keys) to prevent further CEIP related crashes.

A workaround was found quickly:

    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”
    3. Right click on “Command Prompt”, then click on “Run as administrator”
    4. In the UAC prompt, verify that the program’s name is “Windows Command Processor” and then click “Yes”
    5. Right click on the “Administrator: Command Prompt” window’s black area, then select “Paste”
    6. Press “Enter”, you should see “The operation completed successfully”.
    If you see “ERROR: Access is denied”, please make sure you followed Step 3.
    7. Close the “Administrator: Command Prompt window”

Should you encounter any other problems, you might be able to find a solution in the “action center” which you can find in the “control panel”!
