SWX 2018 on Surface Book

I have recently installed SWX 2018 on a Surface Book (16Gb; NVIDIA card).  Initially, it ran ok (small graphics glitch that I won't get into).

Recently, it does not run at all.  I had the same problem when installing and running 2016. The program starts normally but when it gets to the flash screen that says, "Verifying license . . . ." it simply goes away and nothing else happens.

Here are the steps I took to get my 2016 to eventually run:

1)  Full uninstall of SWX

2)   Reinstall w all virus protection turned off

3)  Go into Services and set all licensing to "Automatic"

4)  Restart, turn on all virus, etc.

5)  it worked

I did all of this on SWX 2016 and it worked.  It is not working on SWX 2018.  Extremely frustrating.  As I mentioned, it was working fine.

In addition to the above, I also attempted to go back to an earlier restore point.  This did not work.

I also did a full uninstall, then, went into the registry and killed all folders associate w Dassault, FlexLicense etc.  Did a reinstall.  Nothing.

I know the official company line is that this computer is not supported.  However, it was running fine.  Both 2016 and 2018.

Anyone seen this?  I have been in contact w support and they can't help me.

EDIT:  On SWX 2016, when it did run, it first displayed an error indicating swactwiz.exe was unable to start correctly.

UPDATE: I can run swactwiz manually.  It confirms my license is activated and operating correctly.  I set it to run as admin.  I also did this to SWX 2018.  I then ran compatibility mode on both.  None of these fixed my problem.

UPDATE:  Still having this issue.  A little surprised no one has commented . . . .

I found this thread w the same problem I am having.  Not clear what the resolution was:
