Re: Register COM DLL when it is not a registered reference (late bound)?

Some Windows Installer registration settings obey the per-user/per-system
rules when the registry entries are installed from the MSI file (vsdrfCOM
setting). That makes perfect sense - why should one user's COM objects be
available for everyone? They get registered in HKCU. Regsvr32 and the code
in DllRegisterServer have no idea about per-user/per-system so they register
for everyone. So if you installed for Just me under one account, a client
running under another account won't find the registration entries. As soon
as you run regsvr32 you make it registered for everyone so now your client
finds it - that's the scenario I was thinking of.

The exact error would be interesting. Class not registered, interface not
registered mean different types of registration error.

You're in the framework.setup group here, but this is a C++ regular COM Dll
we're talking about right? Just checking....
