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:
