Hi;

I have written a Word Add-In in C# that uses .NET 1.1. It all runs fine if
just .NET 1.1 is on a system. However, if .NET 2.0 is also installed, then
while the C# part runs fine, it cannot call vjslib 1.0.5000.0 (used for
zip/unzip) - it cannot find the file specified.

I log all assembly loadings, resolution failures, and exceptions. It is
loading .NET 1.1 and trying to load vjslib 1.0 in both cases. And the only
difference is installing/uninstalling the .NET 2.0 runtime.

The problem under 2.0 goes away if I create a windword.exe.config and set
the supportedRuntime version="v1.1.4322". However this solution won't work in
the case of a Word Add-In. Why? Well, what if another Add-In on install needs
a different config file? Then it overwrites mine and my Add-In is broken. Or
I install second and break the Add-In that installed first.

And the really strange thing is, in the case of no config file and .NET 2.0
installed, my Add-In is still started with .NET 1.1. It still wants to load
vjslib 1.0. The problem is it can't find vjslib 1.0.

It seems to me this is a bug - and a pretty serious one at that. Is there
any workaround other than Add-Ins tromping on each other's config file?
