Reason
The Main reason for this error is ‘Your Application uses Microsoft ASP.NET 2.0 AJAX Extensions 1.0 and they had not been installed on your hosting server’
Solution – 1
- Download the ‘ASPAJAXExtSetup.msi‘ installer from Microsoft and run it on the live server. The required .dll files would then be inserted into the GAC
Solution – 2
- Your Server did not exhibit the problem, so server obviously had the dll files. Then The Simple Answer is to place a copy of these following files in the applicatiion’s ‘Bin’ folder
System.Web.Extensions.Design.dllSystem.Web.Extensions.dll
You can find these files at
C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025\

I have installed ASP.NET 3.5, Visual Studio 2008 and the current Ajax release and get the same error.
Does this mean I need to install ASP.NET 2.0 to use these controls ?
.NET 3.5 has ASP.NET AJAX built-in, Visual Studio 2008 and Visual Web Developer 2008 also now have great support for integrating JavaScript and AJAX into your applications
