Can't run ASP.NET MVC 2 web app on IIS 7.5

Ok, this is resolved for me, by doing the following:

Running aspnet_regiis -i in the 32-bit directory c:\Windows\Microsoft.NET\Framework\v4.0.30319.

At this point, I don't understand why 64-bit mode isn't working, but I'm now unblocked. Hopefully this helps anyone else who is having this issue.

I had exactly the same issue, so thanks for your help.

However... did you try running the aspnet_regiis -i command in the Visual Studio 64 bit command prompt (with admin privileges)? When I did that it fixed it for the 64-bit mode.

To clarify, I right clicked on Visual Studio x64 Win64 Command Prompt (2010) and chose Run as Administrator. Then I went here:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319

And did this: aspnet_regiis -i

And now it works perfectly.

Also ensure that you configuration file has the following line otherwise the routing will not work.

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
