Hi Dan, I've got an idea for you to workaround the problem. Something like:
$ WINEDLLOVERRIDES=mshtml= wine cmd /C echo test $ wine regsvr32 mshtmlwill do the trick. Note that we prevent registration of the whole mshtml in the first command, so we have to make sure it's registered later.
I still think that the proper way is to use packages and I strongly recommend it.
