>I don't think that this will make a difference. I'm sure we've both run into more cases of the "appropriate license not found" than we care to admit (at least I have, had one Friday) inspite of reported success by regsvr32. Anyway, I think you might find the answer to the question interesting. I never realized that there were run-time and design-time licenses, but that's the conclusion I've reached.

Usually, you get that message when the COM is registered, but the design licence (a .lic file) is not found. In this case, you can use the COM in your programs (if you write the code by hand), but you can't use it for design. All this relies on the development tool "correctness" to check for the design time licence. Obviously, not all COMs require such a licence, and, also obviously, one can develop design tools that ignore the requirement for such a licence.

So, this licencing method is far from being bullet-proof.
