I have the problem where when I add an add-in to Excel, I get the same
message. I know it is this custom activex control that I have created
because if I take it out of the addin, I do not see this message
anymore. I have even digitally signed the ocx file and that does not
seem to fix the problem. I have already looked at the KB article and
none of the changes to the registry seems to fix the problem either.
If anyone can help me out, that would be greatly appreciated.
