Excel uses old .NET runtime

Peachy one.  I wrote a .NET COM callable wrapper and attempted to invoke it from Excel.  I got:

The format of the file 'xxx.dll' is invalid

fuslogvw confirmed that this was to do with the version of the .NET runtime being used - v1.1.4322 instead of v2.0.50727.


This blog entry describes the problem and the fix for it.
