is that working with InstallShield v12 files ?
A quick Google search, shows up NO. Flexera changed the format for InstallShield 12 (and later).
Now, I’m not going to check that that’s true myself, as I loath the InstallShield for it’s dodgy installation practices. Practices such as spawning processes such as _isdel.exe
From those Google search results, this is the option I would pick:
Universal Extractor is a program designed to decompress and extract files from any type of archive or installer, such as ZIP or RAR files, self-extracting EXE files, application installers, etc. The full list of supported formats can be found in the table below. It’s able to support so many varied file formats by utilizing the many backend utilities listed in the credits at the bottom of the page.
