Brian,

FYI, here is some of the Installshield log from a project set up simply to copy the three dynazip dlls into [SystemFolder]. When I go to build the release, IS does all sorts of processing of these dlls. The final 3 lines show that it is automatically creating registry keys, as you said.

Thanks again,

Larry
