I would like to be able to unzip files from the command line (via a batch file in this instance) on a Windows Server 2003 machine that does not have WinZip installed.

It seems that three files are needed:

  • WZCL32.DLL

However, I get the following error when I try to run WZUNZIP.EXE:

ERROR(C:\folder\WZUNZIP.EXE,139): WinZip is not installed. You must install WinZip in order to use the WinZip Command Line Support Add-On

Does WinZip (or just the WinZip command-line add-on) allow deployment via a simple file copy, or does it have to be installed with the full installer?

Try 7-Zip for this, the command-line version, specifically.

Extract with this command: 7z.exe e

Since you don't need the WinZip GUI, just use Info-ZIP.
