I have no idea if that error is only related to ECE's, I don't write them.
The links you provided both referred to ECE's however. Dmitry might know, he
writes ECE's.

I do know that I've never seen that error for my own addins (COM addins)
written either in managed or unmanaged code, and I've had no reports of that
problem for any my COM addins.

Hi Ken,

Thanks for your reply. We actually have both a COM addin and an ECE,
implemented in the same DLL. I wasn't sure if the error message was
related to the COM or ECE part - do you think it is definitely the ECE
part that is causing the message to appear? The ECE is registered
using an ECF file. We actually have a second ECE in a different DLL
which is registered through the registry (because that is the only way
to get certain functionality) but I'm not aware of a message coming up
for that one.

I will find out whether they use ESM later today. If not then I will
look into opening a support case with MS.

Regards,
Pete.
