Error 5 occurs when registering WinZip

Windows 7 and Windows Vista have security features implemented that prevent you from accessing certain folders.

The Windows 7 and Windows Vista Operating Systems have security rules or User Account Control (UAC) settings that restrict writing data to certain protected folders.

Error code 5 indicates that you don't have the appropriate rights to save data in that folder or save changes to a specific file in the folder.

Please try the following:

1. Click on the Taskbar Start button
2. In the text box just above Start type: C:\ProgramData
3. Press the Enter key on the keyboard
4. Delete the WinZip folder
5. Attempt the registration of WinZip again

If deleting the WinZip folder does not work for you, you might try temporarily turning off the User Account Control (UAC) as follows and see whether that works:

Windows 7:

1. Open the Control Panel
2. Click User Accounts and Family Safety
3. Click User Accounts
4. Click the item labeled, Change User Account Control settings
5. Drag the slider to the bottom and click OK
6. Restart your computer and try the registration again

Windows Vista:

1. Open the Control Panel
2. Click User Accounts under the User Accounts and Family Safety section
3. Click the item labeled, Turn User Account Control on or off
4. UNcheck the Use User Account Control... checkbox
5. Restart your computer and try the registration again

Be sure to turn on the User Account Control again after attempting the installation and reboot your computer.
