Why has the Symantec custom engine failed to deploy?

To install and deploy MetaDefender Core’s Symantec custom engine, certain Registry Keys need to be present in the registry.

If these keys do not exist, the Symantec engine installation process will time out.

To install the Symantec custom engine in MetaDefender Core, you can manually add the missing registry keys by completing the following steps:

1. Open the Windows registry (regedit.exe)
2. Navigate to HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters
3. Create a new Value Name with the type Multi-String Value and the name: NullSessionPipes
4. Save the changes
5. Remove the Symantec engine from your MetaDefender Core system
6. Uninstall the Symantec Protection Engine manually from Windows
7. Navigate to the location where the Symantec engine is located (Program Files\Symantec) and Delete this folder manually
8. Click Update all in the Modules page to reinstall the engine.
