How to manually uninstall Norton Utilities versions 4.0 and 4.5 for Windows 9x

Situation:
You need to uninstall Norton Utilities 4.0 or 4.5, but the usual uninstall routine from the Windows Add/Remove Programs applet in the Control Panel does not work. You already tried to install or uninstall Norton Utilities, but the process did not finish.

Solution:
In this situation, the common solution is to manually uninstall Norton Utilities. However, you may be able to avoid manually uninstalling Norton Utilities with the following method:

1. Delete the Uninst.isu file that is in the Norton Utilities folder.
2. Do one of the following:
   • Reinstall Norton Utilities.
     
     NOTE: If the original installation stopped responding during the online registration or while creating the Rescue set, skip these steps when you reinstall. You can register by telephone, letter, or from the Customer Service web site, and create a Rescue Disk set after the installation is complete. For more information, see How to register your software when online registration does not work. See the Norton Utilities for Windows User's Guide for instructions on creating a Rescue set.
     
   • Uninstall Norton Utilities.

• Make sure there is at least 50 MB of free disk space on the hard drive to which you are installing.
• Make sure there is at least 50 MB of free disk space on the hard drive on which Windows is installed.
• Check the drive on which the Windows swap file is located and make sure there is at least 100 MB of free disk space. The Windows swap file is usually on the C: drive. To check the location of the swap file, follow these steps:
  1. Right-click the My Computer icon and choose Properties.
  2. Click the Performance tab.
  3. Click Virtual Memory. The Virtual Memory dialog box appears.
  4. Although it may be dimmed, the Hard Drive text box displays the drive on which the swap file is located and how much space is available for the file to use.
• If the drive had sufficient free space for the installation and the Norton Utilities installation did not stop responding during online registration or while creating the Rescue disks, then perform a clean boot and reinstall. For more information, see How to perform a clean boot of Windows 95 or How to perform a clean boot of Windows 98.

1. Right-click the Norton Protected Recycle Bin and then click Norton UnErase. The Norton Protected Recycle Bin Properties dialog box appears.
2. Unerase any files you deleted but might want back later. Any files left in the Norton Protected Recycle Bin will be removed from the bin when you uninstall Norton Utilities and may not be recoverable after the uninstallation.

1. Right-click the Recycle Bin icon, and then click Properties.
2. Click the Global tab.
3. Select Use One Setting for All Drives.
4. Click the Recycle Bin tab.
5. Select Standard Recycle Bin.
6. Change the text in the Title box to "Recycle Bin."
7. Uncheck the Show Norton Protection Status option, if possible.
8. Click the Norton Protection tab.
9. Click Remove Norton Protection.
10. Click Empty Protected Files.
11. Click OK twice.
    
    NOTE: If you are unable to remove Norton Protection (Steps 1 through 9), follow the instructions in the section "To replace specific registry values with their defaults" later in this document.
    
    If you are unable to purge Norton Protected files (Step 10), try purging them manually from within an MS-DOS window. If you deleted these files from Explorer or My Computer, instead of from a DOS window, the Windows Recycle Bin has protected these files.

1. Click Start, point to Programs, and then click MS-DOS Prompt. The MS-DOS prompt appears.
2. Enter the following commands at the prompt, pressing Enter after each line:
   
   C:
   CD\
   DELTREE \RECYCLED\NPROTECT
   
3. Repeat Step 2 for each drive on your system, replacing C: with the appropriate drive letter.
4. Type EXIT and then press Enter to return to the Windows desktop.

• SpeedStart: Right-click the checkered flag on the taskbar and choose Close. If you are prompted to start SpeedStart automatically the next time you run Windows, click NO.
• System Doctor: Right-click any sensor displayed in System Doctor and choose Close.
• CrashGuard: Right-click the shield with the blue letter N and choose Exit. If CrashGuard indicates it will start the next time you restart Windows, click OK. Double-click the Norton Utilities Integrator, click Options, and uncheck the Norton CrashGuard option. Close the Integrator.
• Norton Protection: Press Ctrl+Alt+Del. In the Close Program dialog box, double-click Nprotect.

• Method 1 - Restore backup copies of the registry.
  When Norton Utilities installs, one of the first things it does is create backup copies of the Windows registry files. If you have not installed any other programs since installing Norton Utilities, you can return your system to the state it was in prior to installing Norton Utilities by restoring the backup copies of the registry.
  
  If you have installed other programs since installing Norton Utilities, or you updated programs or drivers, this method will partially or fully remove the changes. If you use this method, you will need to reinstall the other programs and again update the programs or drivers.
  
  This method is faster and easier then Method 2. Use this method if you are unable to start Windows, or if you do not want to manually edit the registry and you have the files necessary for redoing any changes made since you installed Norton Utilities.
  
  CAUTION: Method 1 will remove ALL changes made to the registry since Norton Utilities was installed.
  
• Method 2 - Manually edit the Windows registry to remove all references to Norton Utilities.
  This method is time-consuming and tedious. Use this method if you do not have the registry backups made by Norton Utilities or you made many changes to the system after installing Norton Utilities.
  
  CAUTION: Incorrect changes to the registry could result in permanent data loss or corrupted files. Please make sure you modify only the keys specified.

1. Click Start, and then click Shut Down. The Shut Down Windows dialog box appears.
2. Select "Restart the computer in MS-DOS mode" and click OK.
3. At the DOS prompt, type the following commands, pressing Enter after each line:
   
   CD\WINDOWS
   ATTRIB -R -S -H *.DAT
   REN USER.DAT USER.ABC
   REN SYSTEM.DAT SYSTEM.ABC
   COPY SYSTEM.NU4 SYSTEM.DAT Choose Y to replace the file
   COPY USER.NU4 USER.DAT Choose Y to replace the file
