I am doing a patch from the Patch Design view in InstallShield 2009. The previous setup is entirely compressed in the setup.exe, with the language french and English. When I build the patch, I have the error -6415. Cannot generate a primary transform. I have also many warning like this: Patch API could not create a small patch; using whole upgraded file. Including entire file: etc. When I do the patch with the "previous setup" being the uncompressed setup recompiled, I have no error, but the patch cannot be installed on the previous setup. Anyone have any idea where comes from the error -6415? Is it because the 1033.mst and 1036.mst files are not extracted from setup.exe by Installshield? ... View more
