I  am getting the error:

There is a lot of advice out there indicating that asp.net is not installed correctly. The usual fix is to run:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
or
%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i
I have run both, without any errors. I have restarted IIS, but the problem still persists. The site is using an application pool. The app pool is started, .net framework = 4.0, Managed Pipeline = Classic, Identity = LocalSystem.

I've spent the last couple hours trying to figure out what the problem is. I'm hoping someone can help.

Try switching to Integrated mode.

Please follow these steps:
1) Run the command prompt as administrator.
2) Type either of the two lines below in the command prompt:
%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i
or
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
