Downgrading from 2.0 to 1.1

On our new website we decided to use CommunityServer's asp.net portal. We ran into a multitude of bugs and found out that it has issues with .net 2.0. So I went to downgrade to 1.1 but after the uninstall supposedly finished successfully and I rebooted. Nothing had changed, all files were still there and 1.1 now would not install, and IIS didn't think any .net revision was present. So after a botched uninstall and all scripts and attempts to manually uninstall fail how do you downgrade

Thank you everyone that responds :)

There is no downgrade path as such, .NET 2.0 and .NET 1.1 co exist on your system. Instead, you need to find the program aspnet_regiis.exe in the .NEt install folders and run it with the -i command line switch. There's a copy of that program in each .NET version subfolder, just choose the folder for the version you want IIS to use.

If you copy and paste this into your command window, it stands a good chance of working:

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i
