I\'ve had a serious issue with my Visual Studio 2008 setup. I receive the ever-so-useful error \'A problem has been encountered while loading the setup components.
I think this sort of question is entirely appropriate to the forum, especially if an easy solution can be found, as would save others hours of pain.
Unfortunately I dont have the solution, but would suggest (if you haven't already)
Run FileMon to see if the installer is looking for specific files which are no longer there - this may give some clues.
Painful, but try uninstalling other apps based upon the VS shell (eg 2005) first.
Remove the following hot fixes and updates
Restart the PC and try to uninstall now. This worked for me without problems.
Thanks, riaraos, uninstalling KB952241 was the solution for me, too. Before doing that I tried to run the installer from "Programs and Features" and from the installation DVD without success. I did not want to completely remove the VS 2008 installation but only add a few components.
Notes on my system:
Windows 7 Beta 1 Visual Studio 2008 SP1
You should look for the MSI setup logs in the temp directory of your system. They will contain detailed inforamtion about why the setup failed. I had a similar installation problem with Visual Studio 2008 which I was able to resolve by studying the logs.
