Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7000
Description: The ASCTRM service failed to start due to the following error:
The specified driver is invalid.
If the %SystemRoot%\System32\Drivers\Asctrm.sys is removed but the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ASCTRM registry key exists, you will receive this event when the ASCTRM service fails to start.

2. Merge the ASCTRM.REG file with your registry or run regedit /s ASCTRM.REG.
