Powerpoint Add-in with C# and VBA?

[rob.gorrie]

Hey all

Here's an interesting one for you. I have a client who has a
powerpoint VBA add-in from back in like 99. there's a bunch of extra
functionality, developed in C#, that has been built around it that is
launched from the VBA App.

Right now, the VBA add-in is manually installed by making the user go
to tools -> Add-ins, etc. AFTER they install the full application.

While I can still get the users to do this, I'd much rather have a more
elegant solution and have the VBA Add-in automatically registered as an
add-in with powerpoint (98-2003) through a setup project. How would I
go about doing this?

This VBA Add-in has to exist (and cannot be rewritten) because it has
to work back to Office 98 as well....I can't just reserve it to 2000
and above...in addition, the budget doesn't exist to rewrite the whole
thing in .Net.

So what I'd like to do is either:

have the setup project automatically register the VBA Add-in

OR

have a C# add-in launch the VBA Add-in

I haven't worked with Setup Projects in VS.Net 2005 so I'm a little new
at this here

Any help would be appreciated

Thanks
