Cannot load Microsoft.MSXML Version


I am trying to deploy an Ajax-enabled ASP.NET 2.0 web application that leverages NHibernate for OR-mapping.  Works fine locally, but when I deploy to the web server and browse to the Login.aspx page, I get the following error.  Can someone tell me what the problem means?  And if I need to download a new version of MSXML parser to install on the web server, where can I find it?

Server Error in '/' Application.

Unfortunately that doesn't help.  We already had MSXML 6.0 installed on the web server.  I uninstalled, reinstalled, and rebooted for good measure, and I'm still getting the same exact error.
Mmm...I had a similar problem, but with another 3rd party componenty, and installing the MSXML parser solved it.
I'm sorry it didn't work

Makes sense, but what version would this be?  Below is a link to a list of Microsoft.MSXML versions and there is no  Is it possible that any 8.x version would be suitable?
Good link the one you posted. I would try all the one that are 8.0.x.x version, like:

 2.5 SP1     Msxml.dll8.0.52262.5
 2.5 SP2    Msxml.dll, Msxmlr.dll (the last DLL is a                           resource-only DLL)8.0.5718.12.5
 2.5 SP3    Msxml.dll, Msxmlr.dll (the last DLL is a                           resource-only DLL)8.00.6730.0
 3.0            Msxml3.dll, Msxml3a.dll, Msxml3r.dll (the last                           two DLLs are resource-only DLLs)8.0.7820.0

When you install them, you can check in the GAC the version number and the public token, if you find one that matches the web.config assembly definition, it should be the one.
