You only need to set your app pool to .net4 when using v4.5, so I'd probably switch it back to .net3.5, but I'd also check you have the Managed pipeline mode set to "Integrated" and that you have the latest web.config (if you downloaded umbraco 4.0.4.2 today, you should do).
I'd also recommend you read the install guide for .net 3.5 and integrated pipeline mode available on codeplex:
Error 500.19- Issues Starting Umbraco after install
Hello,
I am new at Umbraco and ran into an issue.
I do have the app pool set to .NET v4.0, and am running VS2010.
Please feel free to ask any questions or provide any help.
Thanks much,
A. K.
Which version of Umbraco are you running? 4.0.x or 4.5?
