Error migrating from Windows 32 bit 2003 IIS6 to Windows 64 bit 2008 IIS7

[Sanjay]

I get the following error after migrating our server from Windows 32 bit 2003 IIS6 to Windows 64 bit 2008 IIS7
I installed Telerik Reporting 2010 and also the asp.net radcontrols 2009 in the server and made sure that these files were copied into
the bin folder of the website.
Please help,

Thanks,
Sanjay D Chudasama

From a client computer the error is 404 - File or directory not found but in the server's internet explorer itself the
Error displayed when accessing the website is as follows:

Hi Sanjay,

Could you please confirm a Telerik.Web.UI with version 2009.3.1208.35 is added to the problematic machine GAC?
Otherwise if you what the web site to reference the Telerik.Web.UI dll located in the Bin folder, make sure you are not referencing it with its fully qualified name in the Web.config or on any of the pages.

All the best,
Iana
