InstallShield installer archive is what we're calling the format of the _INST32I.EX_ file included in many Windows software distributions that use the InstallShield installation software. It appears to be a general-purpose compressed archive format, though it's not clear whether it has been used in any other way.

Disambiguation
It is not to be confused with InstallShield CAB, InstallShield Z, or MS-DOS installation compression.
