Office COM add-in will not load after installing

[oded55]

i am writing a C# Power Point add in . the adding integrates and runs
fine on my local machine when running it from the IDE (VS 2005) or when
installing it from the setup project.

the project is a Shared Add-In, i followed the Microsoft article from

http://support.microsoft.com/kb/302901/EN-US/

when i used .Net 1.1 with VS 2003, i had no issues , but now with
VS2005, i just cant get it to work on any other computer, although it
works fine on the development machine.

anyone faced a similar problems before and know where i should look
for, or better, know the solution for that?

are there any specific setup project settings that are diffrent with
..NET 2.0?

thanks

Just a thought but could it be related to the security/permissions set on
the target PCs?

I hit this same problem and fixed it by increasing my version number and
setting LoadBehavior to 3.

Unfortunately, this didn't help, i can see that everything is installed
at the right places, including the registry keys, but the addin is not
loaded with the application.

if i install it on a system with VS (even different computers) it
succeeds

I Tested it on few PC, with fresh OS (WinXP installed)
nothing with security was modified.

Hi;

If it's any consolation, I'm now having the same problem with my Add-In.
Unfortuantely there is no way to find out why Word or PowerPoint is unhappy.
I've gone down this road before - there is no visibility into why Word fails
- NONE.

Hi,

So, what are the steps are you taking? i am thinking of going back to
..NET 1.1 , it is very painfull, but i cant find any solution for the
problem (security or other).

Thanks

I found the problem in my case - KB907417. My guess is VS 2005 installs it
silently.

Dave,

KB907417 Worked for me, although they dont mention PowerPoint addins
there.

thanks a lot.
