Problem with AddIn in Localized/In (Swedish) version of MS Office

[Dan WB]

Hi!
I've created a COM Add-In in C#, Visual Studio 2005. It works just fine on
all English versions of MS Word and MS Outlook I've tried it on, but fails to
load at all on any Swedish versions of Word/Outlook.

Steps to reproduce the problem:
1) Use the Visual Studio 2005 Shared Add-in Wizard to create a new Add-in
project and choose Word and Outlook as application hosts.
2) Add a reference to Windows.Forms and then add a MessageBox.Show to the
OnConnection method
3) Build the project and setup file.
4) Move to another machine and install the new add-in.
5) Start MS Word 2003 or MS Outlook 2003
6) Notice that if the target machine uses an:
6.1) English version of Office, then the MessageBox appears
6.2) Swedish version of Office, then the Add-In doesn't get loaded and no
MessageBox appears

I have got exactly these results on three different english systems and four
(completely) different swedish systems.

Question: how shall I make a COM Add-In built in C# loadable in a swedish
version of Office 2003?

PS. I'm building on a machine with an english version of Office - if that
should make any difference.
