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 encountered the same problem and found a very easy solution.Go to the following Link: http://msdn.microsoft.com/en-us/vs2008/bb968856.aspx
and run VS AutoUninstall tool .This will automatically remove all the components of VS 2008.
Cheers
