Then follow these steps below to replace software dynamic library file, then continue using the software as before:
1. Next to the clock in the lower right corner of the screen click the system tray icon with the spanner then select option Shut down System Suite/Fix-It Utilities.
If there isn't such icon that means the software isn't running, so please proceed forward with the rest of these instructions:
2. Replace the StartupCommanderEngine.dll file located in the application install directory with this one here
(default location on 32-bit system type is C:\Program Files\Avanquest\SystemSuite\ or C:\Program Files\Avanquest\Fix-It Utilities\ On 64-bit system types the install location is in C:\Program Files (x86)\Avanquest\)
Alternative approach is to rename the original StartupCommanderEngine.dll to StartupCommanderEngineOLD.dll then paste the new one you've downloaded.

3. Restart the computer to apply changes.
