Customers that purchase a multi-user license, are given a WinZip Registration File. If you buy WinZip from an authorized reseller, you receive a WinZip Activation Code. If you purchase your software directly from WinZip, you receive a WinZip Registration Code. WinZip Activation and Registration codes are used to install your WinZip software.

This upgrade scheme was discontinued as of version 10.0. From version 6.0 until version 9.0, registered users could download the newest versions of the software, enter their original registration information or install over the top of their existing registered version, and thereby obtain a free upgrade.
