2sec. so I Re debug it this time it come up with Outlook experienced a
serious error the last time the add-in 'dc-dmcrm' was opened. Would you

the same think happen so it is not my code.

Also i can debug it with the same code on the other PC!!!!

This will happen if you have both 1.x and 2.0 versions of the .NET Framework
installed on the machine. When Outlook loads the runtime by default it will
load the latest version (2.0). The problem is that VS2003 is now trying to
debug against the 2.0 CLR and it crashes. That causes Outlook to crash as
well and as far as it can tell your add-in is the problem so it offers to
disable it.

You can fix this by supplying Outlook with a config file that tells it what
version of the runtime it should load. Create a new file named
outlook.exe.config with this text (you could also specify the 1.0 CLR if
that's what you're targeting):


<requiredRuntime version="v1.1.4322" safemode="true"/>



Put the file in the same directory as Outlook.exe. The next time you try
debugging Outlook will know to load CLR v.1.1 and VS2003 won't freak out.
