I want to run MVC 3 on my Windows 7 32 Bit machine. I have Visual Studio 2010 and I can create ASP.NET MVC2 projects there. But now, I want to install MVC 3 in my machine. So, I tried the online installation using Web Platform Installer from http://www.asp.net/mvc/mvc3 link. After installation, I didn't find the ASP.NET MVC 3 Web Project Template in my Visual Studio 2010 Project Templates. So I again downloaded the Offline Installer from same link. But I got error when I ran the installer. Clicking on the Log file I got:

OS Version = 6.1.7600, Platform 2

CommandLine = h:\temp\ext6142\setup.exe

  • Did you install the last MVC3 (final) ? http://www.asp.net/mvc/mvc3 Did you try to do a Windows Update before installation ? – Spilarix Jan 18 '11 at 09:44

After installing from web platform, I didn't check the selected .NET Framework Version in Visual Studio Project Template when I wanted to create a new project in MVC 3. Default .NET Framework was 3.5 in the visual studio of my machine. So MVC 3 project template wasn't showing in the project templates.
And, without uninstalling the existing MVC 3, when I again wanted to install MVC 3 from offline installer, I got the error I mentioned in my question. It may happened because either performing same installation or the file was corrupted at the time of downloading or any other issue.
Later, after uninstalling MVC 3 from control panel, I again run the web platform installer to install the MVC 3 and this time I check the selected .NET version. I selected .NET Framework 4 and MVC 3 project template is now appeared in visual studio's project templates.

My computer had trouble uninstalling an older MVC3 RC. Fix:

  1. Remove the trailing backslash from the following registry keys:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\4.0.30319.0\Path
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET\4.0.30319.0\Path

  2. Uninstalled the old version of "Microsoft ASP.NET Web Pages".

  3. Add the trailing backslash back to those keys.
  4. Install MVC 3.

In any case it's good idea to download the offline installer. The web one doesn't care about error messages, and just shows success.

In my case it was c# async CTP that was blocking the installation - the offline installer at least told me so:)
