Make sure your COM server is registered before you import it...

THere are also security issues - if you're running under UAC you won't be a true Admin account and so you can't register the COM component or register it in COM+. Make sure you run regsvr32 on the DLL first and see if that works. Once it's registered then run Component Services and Import. You may have to run with RunAs Administrator both for the command prompt for regsvr32 and Component Services if you're running under UAC.

>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.
