Statement
KB 125806 and 125804: registration information for a major version also registers its minor updates but not another major version (a WinZip 25 code does not work with WinZip 26). The multi-user licence file likewise must match the installed major version.
Applies when
Reinstalling or reimaging with an older registration.
Applies to
Perpetual WinZip, Courier and Self-Extractor registrations.
