Hello,
What you need to do is delete these folders:
C:\Program Files\Symantec\Ghost
C:\Documents and Settings\All Users\Application Data\Symantec\Ghost
Then open the registry editor and make a backup. Then do the following:
1. Delete the following key:
HKLM\SOFTWARE\Symantec\Symantec Ghost
2. Browse to HKLM\SOFTWARE\Symantec\InstalledApps and delete the Ghost value.
3. Browse to HKCR\Installer\Products and find the GUID folder for Ghost. Just click on the top folder, review the information in the right pane for references to Symantec Ghost and delete any folders referring to Ghost.
4. Delete these keys:
HKLM\SYSTEM\{all controlset folders}\Services\NGSERVER
HKLM\SYSTEM\{all controlset folders}\Services\NGDBSERV
Then reboot the machine. This should allow installing the new version.
Thank you,
Randy
