The person getting this error is running a local IIS and has .net framework installed. We are all sharing this web site project via source control, so would a change in actual paths between different people who get the files from source control make a difference?

Also, I installed the IIS on his machine and registered the .net framework with aspnet_regiis -i i also installed Ajax 2.0. i checked on his machine, and that assembly is in his GAC with an identical version number and PublicKeyToken

I checked the global assembly cache, it's there. It's the exact correct version and PublicKeyToken. C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025 also exists

I suppose you don't have Ajax extensions installed properly or that the installation is corrupt. Try reinstalling it. Here' s the Link for ASP.NET AJAX 1.0 installation if you want

Download and install it. Hope this solves the issue.

I already gave him this link and he said he installed it. Wouldn't the folders and files that I said exist on his machine mean that this is already installed?? The person I'm working with "can't be bothered" with this, so I have to ask these questions rather than merely try it on his machine. He wants the solution without him having to try things. In other words, he wants a home run first time at the plate.

A question, the local IIS have app's with framework 1.1 and framework 2.0?

Ajax has conflict with the different frameworks of .Net  because use different XHTML code.

Try to write in the wbe.config this line.

  <xhtmlConformance mode="strict" />

Also create different application group for each version of .Net Framework in IIS.
