LogMeIn (LMI) Antivirus (AV): Scans initiated from Admin Portal never run

We have "silent mode" enabled on a few of our LogMeIn Antivirus policies.  Thus, we cannot open the LogMeIn AV application on PCs that have silent mode enabled.

Often, I need to initiate a scan on one of the PCs that have silent mode enabled.  When I initiate a scan through the Admin portal, the scans never run.  Or, the Admin Console never reports that a scan has run.

After initiating a full scan, I leave a PC on for hours.  Again, the Admin portal never reports that a scan has been run.

We are using the latest version of LogMeIn on our Windows 10 PCs (4.1.0.14344).  This problem is present in older versions of LogMeIn as well.

With that said, is there a way I can initiate a scan on a PC that has silent mode itself by using a command line or something like this?

Thanks.
