This appears to be an issue involving permissions in the Windows Registry. When WinZip attempts to create or delete Registry entries appropriate permissions are required. If the appropriate permissions are not present for the 'user' involved this error will occur. Please do the following a. Make sure WinZip is not running anywhere. b. In Windows Explorer (or My Computer) open the "Program Files" folder and then the WinZip subfolder. c. Press CTRL + A on the keyboard to select all the files in the folder. d. Right mouse click in the highlighted area and choose "Properties". e. Make sure the "Read-only" check box is blank (you may have to click the box more than one time) and click OK. f. Click on the Start button on the taskbar. g. If not Vista: Click on the "Run" menu item If Vista: Click on "All Programs", "Accessories". Right click on "Command Prompt" and choose "Run as administrator". h. Enter: "c:\program files\winzip\winzip32.exe" /uninstall i. Press the "Enter" key on the keyboard. j. Follow the steps. k. WinZip should now be uninstalled. l. To complete the cleanup, please go to "Add/Remove Programs" in the Control Panel ("Programs and Features" in Vista) and remove WinZip. m. You should be all set now. Please let me know if you have any further questions.
