This is an old post, but for anyone else who has this problem, I fixed mine on XP SP2.

I have a VB project group, in which one of the ActiveX DLLs was lodged in a COM+ component. The COM+ component was running under a different user account than my logged in user account. If I either deleted the COM+ component, or used my log in account for the identity of the COM+ component, it worked.

I don't think there is a way to run in the IDE with mismatched COM+ identities and login identities.

I have just started experiencing this problem.

Every .vbg project on my system is now giving this error.

A normal .vbp runs fine. Just not Groups. Even if I create a new one.

The only thing I can think of is that I installed a new hard drive and transferred the system across. But surly this wouldn't do it ?

I have reinstalled VB but no go.

I have checked Microsoft but I can't find anything there.

Appreciate any help .. Thanks
