Today I wanted to experiment a little bit with ASP.NET MVC2. I downloaded the bits from Microsoft Download and clicked on the executable. Unfortunately an error occurred and the installation was stopped.
No worries, this is an easy fix. If you click on Details, then youâ€™ll see whatâ€™s going on. From my previous Visual Studio 2010 release, I still had an older version of ASP.NET MVC.
I just removed ASP.NET MVC 2 and then tried to reinstall, this time it succeeded!
