MORE INFORMATION

Steps to reproduce the problem

Run the following command to uninstall the 64-bit version of ASP.NET 2.0:
Framework64\aspnet_regiis -u
Run the following command to switch IIS to run in WOW64 mode:
cscript DriveLetter:\inetpub\AdminScripts\adsutil.vbs set w3svc/AppPools/Enable32BitAppOnWin64 1
