It took while before I could respond as I had to restore my laptop first. Never the less, back again. The installation of VMwWS 14 went well, after a reboot however the VMware Tray app couldn't start. Naif as I was updated the version to 15 and there is where it went wrong. Even restoring to an earlier (manual created restore point before installing VMwWM) restore point was challenging.
So, now (after updating Windows 10 to the latest, installing the latest .NET Framework and DirectX) the VMware Tray crashes (0xc000007b), and VMware Workstation is still not starting.
Back to square one ... any ideas on how to tackle, or what to look for are welcome!
