Yesterday, I wrote about troubleshooting Windows MSI Installers and talked about the pain we here feel when an installation fails. Turns out, it’s not always our fault. ;) It appears there’s a hotfix released for Visual Studio which addresses a problem with installing ASP.NET MVC when you have a third party add-in installed. I mentioned the three above because they are among the most commonly used add-ins which run into problems.

You can read about the Hotfix on the Visual Web Developer blog or simply go here to download it.

Note, that this doesn’t solve the problem for all add-ins. For example, someone reported an installation failure when they had Clone Detective installed. Uninstalling Clone Detective, installing ASP.NET MVC, and then reinstalling Clone Detective solved the problem. We’re still looking into why our installers are having problems with these add-ins.
