New install, back office won't run properly, server error

I installed Unbraco 5.1 using the MS Web Platform Installer on a Win7 machine running IIS 7.5. When I log on to the back office a Server Error window pops up immediately but the message goes by so fast it was hard to capture it before the window cleared. (The message is pasted below.) I can then close the error window but the contents panel on the left just displays the "loading" animation and never finishes. Very frustrating to get so close to having it running. Anyone have an idea?

Hi Jim R and welcome to the community! :)

Do you have both MVC 2 and MVC 3 installed on your machine? I have a suspission that might is the issue here.

I'll encourage you to download webmatrix and try installing it from the web app gallery. Be sure to choose "Umbraco CMS 5", since both v4 and v5 can be installed using webmatrix.

The benefit of using Webmatrix is that it also checks what dependencies you need in order to run Umbraco so it will notify you and ask you to download these as well.

Hope this helps.

/Jan
