How do I revert to my licensed earlier version of Winzip?

If you have installed the latest version of WinZip over your registered, earlier major version, WinZip will run as the evaluation version. If you do not have current upgrade assurance and decide that you do not wish to upgrade it will be necessary to download and install the final build of your older WinZip version.

Before installing the older version you will need to uninstall the newer version. Once the uninstall has completed you can install the version to which your registration applies. If your earlier version is WinZip 11 or later a file that was created when you entered your registration will still exist and WinZip will automatically run as registered. Otherwise, you will need to enter your registration information when you run WinZip.

If you do not have your registration information or you are not certain what version you have registered, please try the Quick Search section of our What is my registration code? article. Quick Search will send details to you automatically. If you do not remember the email address under which you registered or no relevant information is found, please enter the requested information in the Detailed Search section of this article. That will help us to locate your registration record and send you the information.
