I thought I had ASP installed right (and know I did b/c SQL Reporting doesn't install without this) but at some point these settings were changed. I followed these instructions (link below):
ASP.NET 2.0, 64-bit version
To run the 64-bit version of ASP.NET 2.0, follow these steps:
1. Click Start, click Run, type cmd, and then click OK.
2. Type the following command to disable the 32-bit mode:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0
3. Type the following command to install the version of ASP.NET 2.0 and to install the script maps at the IIS root and under:
%SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i
4.
Make sure that the status of ASP.NET version 2.0.50727 is set to
Allowed in the Web service extension list in Internet Information
Services Manager.
