SolidWorks 2018 Won't start up

Installed SW 2018 on 3 machines.  It was working OK on all of them and then boom it stopped.  Stopped meaning when you click the SW icon on the desktop nothing happens.  No error, no startup, nothing.

We run off a license server.  Both the server and Windows meet the hardware/software requirements for 2018 (Win 7 and Microsoft Server 2016).  Installed SW2018 SP3 and rolled back the latest windows update.  Didn't help.

Our VAR is no help.  They say it must be a windows issue and without an error message they have no direction to offer support.

Any ideas?
