Technical Solution



You are attempting to install Symantec AntiVirus Corporate Edition or Norton AntiVirus Corporate Edition under Windows NT/2000/XP/2003. During the installation, you see the message "Rolling back...."

You may notice that the HKEY_LOCAL_MACHINE\Software\Intel\LanDesk\VirusProtect6 registry key still exists, but the permissions are incorrect. You may be unable to modify or delete the registry key.


Because this situation has a variety of causes, no one solution will work in every case. To solve the problem, try each solution in the order that it appears and then test to see if it fixed the problem. If it did not fix the problem, try the next solution.

Possible solution 1
If the installation stops responding or rolls back, open the Task Manager and see if Lucoms~1.exe is present. If so, cancel the install.
  1. Download and install Lusetup.exe.
  2. Install Symantec or Norton AntiVirus.

Possible solution 2
This error can occur if the Symevent files fail to install correctly. To correct this problem, download and run Sevinst.exe.
For more information, see the document Updating the Symevent files.

Possible solution 3
In some cases reported to Symantec Technical Support, the problem was related to security permissions. Look in the MSI log file to see whether it indicates which file was last tried prior to the roll back. In all cases, insufficient rights were available to that file.

For help with installation problems related to rights and permissions, follow the directions in the document for the version of the program that you are using:
Possible solution 4
If the previous solutions in this document did not fix the problem, then it is necessary delete a shared Symantec folder. If you have no other Symantec programs on your computer, delete the following folder:

C:\Program Files\Common Files\Symantec Shared

If you delete this folder while other Symantec programs are installed, you may have to uninstall and then reinstall those programs.
