If i undestood you correctly
you took some unrelated dll (advapi32.dll, for example) and renamed it to license.dll (your problem dll) -> all works correctly. Yes ? but it does not mean
that there is no checksum test in license.dll.

I think there are self - written (not operation system) checksum test in your license.dll in DllMain function of your license.dll.
