Sounds like you are using a version earlier than 2.50 which in its SHAREWARE incarnation was released as a SFX called PK250DOS.EXE

PKWARE appear to have now removed their own public download copy (which lived here: ftp://ftp.pkware.com/PK250DOS.EXE ) and I also noted that DOS as an option has also now been dropped off their contact sales page but as per this page it appears to still be available to buy/register.

 I seem to remember seeing some tools in my BBS days to modify these fields.
