Visual Studio setup problem - 'A problem has been encountered while loading the setup components. Canceling setup.'

Question

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.

Answer 1

I had the same error message. For me it was happening because I was trying to run the installer from the DVD rather than running the installer from Add/Remove programs.
