Fix error 5 occurring when registering WinZip

17 users found this article helpful

The Windows 11, Windows 10, Windows 8, and Windows 7 operating systems have security rules and User Account Control (UAC) settings that restrict writing data to certain protected files and folders.

Error code 5 when registering indicates that a registration file from a previous version exists, that this file and probably the folder in which it resides have permissions restricted to an administrator, and that the user who is installing does not have the required permissions to save or edit the registration file. If this error is encountered, the best solution is to delete the particular folder and its files, and then let WinZip recreate them with the correct permissions. For this solution and to see other work around solutions, please click the link for your Windows version below and follow the detailed Error code 5 steps.
