If you are not able to uninstall WinZip using the appropriate applet in the Control Panel, you may be able to uninstall manually. Uninstall issues can occur for a variety of reasons. It is even possible that you will not find WinZip in the list of programs that can be uninstalled.

You may want to refer to some of the information in Command Line Basics when following these instructions.

To uninstall manually:

  1. Open the WinZip folder, usually in the Program Files folder
    Note: If you have a 32-bit version of WinZip on a 64-bit version of Windows, you will need to open the Program Files (x86) folder
  2. Press CTRL+A on the keyboard to select all of the WinZip program files
  3. Right click anywhere in the highlighted area and choose Properties
  4. Click the box next to Read Only until it is clear (no check mark, not colored)
    Clear the Read Only box
  5. Click OK
  6. Select the radio button next to "Apply changes to the selected items, subfolders and files" in the Confirm Attribute Changes dialog
    Clear the Read Only box
  7. Click OK
  8. Click Continue in the Access Denied dialog, if it displays
  9. Right click Start and choose Command Prompt (Administrator)
    For Windows 7 and Vista, you will need to find Command Prompt on the Start menu, right click, and choose Run as administrator
  10. In the Command Prompt window type the appropriate line below (32-bit WinZip or 64-bit WinZip):
    "%ProgramFiles%\WinZip\winzip32" /uninstall
    "%ProgramFiles%\WinZip\winzip64" /uninstall
  11. Press Enter on the keyboard
  12. Respond to the dialogs that display to uninstall WinZip
    Note: Versions earlier than WinZip 19 should skip to step 17
  13. Highlight and copy: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup
  14. On the keyboard, press Windows key (the Windows key)+R to open Run
  15. Right click in the Run dialog and choose Paste and then click OK
  16. In the Startup folder that opens, delete both the FAH shortcut and the WinZip Preloader shortcut
  17. Restart your computer
  18. Delete the WinZip folder in the Program Files folder (removing all remaining files and subfolders)

If WinZip was on the uninstall list when you first tried uninstalling, continue with the steps below.

  1. On the keyboard, press Windows key (the Windows key)+R to open Run
  2. In the Run dialog type: regedit and click OK, which will open the Registry Editor
  3. Click Yes in the User Account Control dialog (if necessary)
  4. Browse to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\

  1. Click on {CD95F661-A5C4-44F5-A6AA-ECDD91C240??} to display its contents in the right pane of the Registry Editor and make certain that the DisplayName string value shows this to be WinZip
  2. After clicking {CD95F661-A5C4-44F5-A6AA-ECDD91C240??} to select it, press Delete on the keyboard
  3. Respond to the warning dialog that displays and close the Registry Editor
