Internal Error 2753 when installing WinZip

An Internal Error 2753 message usually indicates that something from a previous install or install attempt is interfering. The first step would be to try to uninstall WinZip. If you already tried to uninstall, but were unable to do so, the next step would be to try Manually uninstalling WinZip, making sure to restart the computer afterwards. You should then check the Program Files folder and delete any remaining WinZip files.
