While installing Symantec AntiVirus Corporate Edition server or client, you see the error message "InstallShield Wizard Completed - The wizard was interrupted before Symantec AntiVirus Corporate Edition could be completely installed. Your system has not been modified. To complete installation at another time, please run setup again. Click Finish to exit the wizard."
Symantec AntiVirus is not installed.
Before you begin: If you see this error message when you install Symantec Client Security 3.0 or Symantec AntiVirus Corporate Edition 10.0, see the document Error: "The Wizard Was Interrupted..." or "Error: 'msxmlx.inf' with error code 1 (0x1)" during installation in addition to the solutions in this document.
This problem has more than one cause, so more than one solution is provided. To fix the problem, try each of the following solutions in the order that they appear.
Start the Telephony service
This problem can happen when you install Symantec AntiVirus server with AMS to a computer that has the Telephony service disabled. To fix the problem, start the Telephony service, and then install Symantec AntiVirus server again.
To start the Telephony service
Perform a basic test of the installation process
Because this error message is generated by the installation engine itself, it is important to test the basic operations of the installer by running a specific file. This process only tests for the most general of problems, and may complete successfully regardless of other possible Windows problems.
To test the basic functionality of the installation engine
If you see an error message while running the file, then use this error message to search the Symantec Knowledge Base for a solution to that problem. If you do not see an error message after running the file, then do one of the following:
Remove legacy Norton AntiVirus consumer software components
In some cases, leftover components of Norton AntiVirus consumer software can cause Symantec AntiVirus Corporate Edition to fail. Follow the steps in this section to remove any remaining components.
WARNING: We strongly recommend that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify only the keys that are specified. Read the document How to back up the Windows registry for instructions.
To remove legacy Norton AntiVirus consumer software components
After you have removed all legacy components of Norton AntiVirus consumer software, then update Symevent. Symevent is a shared component across many Symantec products, and in some cases must be updated prior to installation. For details, read the document Updating the Symevent files.
After you update Symevent, restart the computer and then install Symantec AntiVirus again. If you still see this error message, then go on to the next section, "Check the operating environment."
Check the operating environment
If you have tried the other solutions in this document but the problem still exists, then follow the steps listed here in the order given.
To verify that you have enough free space on your hard drive
Before reinstalling Symantec AntiVirus, verify that you have adequate drive space for the installation. A server installation requires 450 MB of free space, and a client installation requires 50 MB. If you are installing from a CD, then parts of the CD may be extracted to the Windows temp directory during installation, so more space may be required in that case.
To scan for viruses with current virus definitions
A virus infection may cause this problem. Do one of the following:
If the affected computer is a mail server, you must set exclusions before you run the scan.
For details, read the document Installing Symantec or Norton AntiVirus Corporate Edition on mail servers.
If you cannot download Intelligent Updater definitions, you can run an online scan. The online scan will detect but cannot remove currently known viruses.
To run a full online scan, go the Symantec Security Check Website and follow the prompts.
To check for virus definition corruption
If Symantec AntiVirus is currently installed, make sure that the virus definitions are not corrupted.
For directions, read the document How to determine if virus definitions used by Symantec AntiVirus Corporate Edition are corrupted.
To delete the InstallShield\Driver folder
To delete any leftover .msi files that are part of the Symantec AntiVirus installation
In addition, download and run the Windows Installer CleanUp Utility. Find and remove all entries for Symantec AntiVirus and Norton AntiVirus. For more information, read the Microsoft article Description of the Windows Installer CleanUp Utility (article 290301).
To delete temporary files
To update the Oleaut32.dll file
The installation of other programs may change the version of the Oleaut32.dll file. If the version of this file is earlier than 2.40.4515, then update the file using one of the following methods (either of these methods should update the Oleaut32.dll file to 2.40.4515):
To temporarily disable the use of long file names
To verify Distributed COM properties
To verify registry permissions
Verify file system permissions
If your drive is an NTFS volume, then verify that the System and Administrator accounts have Full Control access to all relevant folders. For more information, see the document Troubleshooting Symantec AntiVirus Corporate Edition installations: Checking rights and permissions.
Remove Symantec shared files
WARNING: Do not perform this step if there are other Symantec products installed on the computer. Following this step with other Symantec products installed will cause them to need to be reinstalled.
If and only if there are no other Symantec products on the computer, delete the \Program Files\Common Files\Symantec Shared folder.
Reinstall Symantec AntiVirus
In some reported cases, moving the installation files to a folder on the root of drive C has fixed this problem (either from a download or the CD), or generated a more descriptive error message.
If you still cannot install Symantec AntiVirus, then do one of the following:
Read the following Microsoft Knowledge Base articles for additional information on Windows installer problems:
