Windows 7 and Silverlight Developer Tools Installer

Kudos to the Windows 7 team for building an awesome feedback loop. 

Lately I had several tools fail when I tried to install them.  Today the Windows 7 notification window gave me the solution.  The crashes were not caused by the installers themselves but by the Customer Experience Improvement Program (CEIP).  You know when you check the box to send anonymous feedback to Microsoft?  Well it uses this system to send information about what you are installing and which options you selected. 

This is useful information to us because it helps us to know what things people find useful.  The solution to fix my installer problems for now is to disable this feature with a regkey entry.  Windows 7 told me exactly what to do in step by step fashion.  The most critical step is the following

In the Administrator: Command Prompt window, type or paste the following text at the prompt:

reg delete HKLM\SOFTWARE\Microsoft\SQMClient\Windows\DisabledSessions /va /f


Once I did this – the Silverlight installer worked without any problem at all!

    This is an important fix for people who can’t install vs2008 on Win7. I have seen many complaints about "setup encountering an error and stopping" (as happened to me).

    I had just about given up when I saw your article. This fix allowed vs2008 install with no problem.

    It needs to be more widely publicized —

    I agree this needs to be more widely publicized.  I was unable install Silverlight (a MS product) nor my AT&T Communication Manager for my wireless card.  I was about to take the card back before I googled (sorry…I don’t use Live) and found this article.

    MS should assign someone to do a weekly ‘Beta Checkin’ that listed the most common issues and questions that people have…and their answers.  Just one page each week.  Then send it out to the news outlets (Cnet, Engadget, Gizmodo, Ars, Tom’s Hardware)…

    Then…maybe as they fixed bugs..they would put it out there that they were fixed.  It would really be like the world community is participating in a ‘world beta’… then everyone would be ready to purchase the new OS this fall because they know everything about it, how to use the new features, and they were a ‘part of building of a new OS’….they feel a sense of ownership.

    But..that’s just my 2cents.

    When I try to run that command, even in Admin mode, I get Access Denied.

    Brant — you must be running an administrator version of the command prompt. Check this article, about halfway down. called Creating an Administrator Session Shortcut:
