I had an issue installing Visual Studio 2010 RC on Windows XP SP3?
(Have installed same ISO package on Vista and worked fine…)
Setup would fail no matter what I tried:
Microsoft Visual Studio 2010 Ultimate RC Setup
A problem has been encountered while
loading the setup components.
Canceling setup.
I found a solution by “Mikael Söderström” on MSDN Forums:
