CORK
From Just Solve the File Format Problem
CORK is the signature of a compressed file format used for installation by a small number of Windows 3.x software products. It is apparently associated with a company named Omega Logic.
It's not clear whether the installer was released as a product, or only used by Omega Logic and its partners.
Format details
The compression scheme is ARC method #8.
