I've been working on an internal website for quite some time now, maintaining it for a client.Other than a few bugs, the website is working as intended.But then, all of a sudden, the error in question appears. This has never happened before.Here are the software we used:. Windows Server 2008 R2, 64bit. Visual Studio 2005 as the IDE of choice.

ASP.net / C# for the website.NET 2.0. IIS, for the website hosting.

I see no reason why the website, which has been built using ' Mixed Platforms' since long before my time, would suddenly cease operating on the OS it was deployed to, also long before my time.

As no one else uses that server, how could it suddenly generate such an error? It's not like someone can just go in there and uninstall stuff - Windows Update, maybe?Here's a screenshot of what I found on the OS in C:WindowsAssembly:Strange thing is, I found the same thing on my local test dev PC, with the addition of some version 13 parts for another program I'm working on.

The website works fine on my local test dev. On the live server, it does not.
