Catch System.IO.FileLoadException at program startup

In my program I have a neat exception handler, which will catch every uncaught exception in my program and creates a file or even will mail me the error, including a callstack etc when something goes wrong.
But when one of the dll's does nog have the right version I get an 'System.IO.FileLoadException', which fires before the 'main' is entered and thus before I could install my exception handler.

How can I catch this 'FileLoadException' in code?

No this blog does not help.
It points out all things I already have in my unhandled exceptionhandler. But this code is wired after you start the Main() of your application. If one of the DLL's your exe is depending on is not there or has a wrong version number, the FileLoadException is fired and this is done BEFORE you enter Main().

I want to fire some code which lives in the main executable, if one of the DLL's it's depending is not valid. I then want to report this fact in a nice logfile and exit gracefully.

You could create a Loading Program which simply, and is good practise to do so, creates a separate app domain for your program, and your program then runs inside this separate App Domain.  You would then be able to catch any expection which occurs in your target program before the Main().
