I have an app that I installed on a W XP. It's got an exe and a dll.
I published the component in Com+. All this in one single pc. And it works fine.
I tried to do the same thing on a W 7 pc. And I can´t even get started. When I try to add the dll to Component Services you have to choose the dll, but when I do it does not add it, instead I get an arror message saying that the dll file coul not be added. The .tlb file is in it's place.
I tried the same thing with code

it didn't work either.
The strange thing is that in another pc that same code run with no problemn at all, and I got the dll with all it's methods in Component Services.
Thanks for any idea.
