Hi, Am trying to install Atlas on local developmenet PC (Windows 7, 64-bit, IIS 7.5) and ran into an issue where the application did not run correctly.

Tried both the manual install and the web platform install. The symptoms of the issue was that a blank page was returned to the user and no error logged anywhere. Upon looking at how IIS was configued, it turned out there were errors displayed in IIS when trying to view the .NET Compilation. One error displayed was: Unrecognized element is 'folderLevelBuildProviders'

Anyway, the source of the problem was that IIS was installed AFTER VS2010 and the .Net 4.0 framework.

And the solution to the problem is to re-register ASP.Net 4.0 with IIS. Run the following command from the 64-bit .Net framework folder:

aspnet_regiis -iru

Just thought it would be good to log this in case others have a similar issue.
