Fixed the issue by not doing any of this, but rather changing the Application Pool Identity to NetworkService rather than the default. :)

Can windows 7 gets more frustrating with security issues, 3 days to configure IIS 7 and now a whole day just to get the AJAX toolkit running!!!!!! what a pain. Can someone please tell me where do you see “unblock”?!? When I right click on the DLL, I don’t see the unblock option. Any help would be greatly appreciated.

Thanks Simon. That was a great help. I unblocked the dll and did a IIS restart and that fixed the issue.

Simon, thank you very much. “Unlocking” the files solve my problem.

its is only because of ‘required field validator controls’ in that page, just remove it

Thanks Simon, you are a star… Unblocking resolved my issue, all it needed was a IIS restart… Windows 7 is a learning…. I am getting there slowly…

Cheers

Thanks for this info. I have a site that has been running fine on Windows 2008 server,32 bit and Windows 7 64 bit.
Just deployed it to Windows Web Edition 64 bit for a client, and most of the site worked, except for one page which crashed with this error.
Unblocked AJAX Toolkit DLL, and all works fine now.
As the AJAX toolkit has been preventing me from migrating the site to .Net 4, I think it is time to junk it…
