An issue with the Customer Experience Improvement Program (CEIP) client in
Windows 7 beta is causing Explorer and some MSI-based installers to stop
To solve this problem, follow these steps:
Click the *Start* button , click *All Programs*, and then click *
Right-click *Command Prompt*, and then click *Run as administrator*. In
the *User Account Control* window, verify that *Program name* is *Windows
Command Processor*, and then click *Yes*.
In the *Administrator: Command Prompt* window, type or paste the
following text at the prompt:
*reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions
Press Enter to install the solution.
If *The operation completed successfully* displays, close the
Command Prompt* window to complete this procedure. If *"ERROR: Access is
denied"* displays, repeat this procedure from the top, making sure you
clicked *Run as administrator* in step two.
