Hi Eddie,
thanks for the fast reply. This worked. The second system updated now directly without going via Express first. I had noticed that the VBar Control Manager 2.1 keept dropping the USB connection, which was not the case with VCM 1.3. I then did the updates on my older notebook (both Win 10 64bit) and there it ran stable. Maybe this was the issue in the first place.
Anyways, both of my VBars are now running 6.4.45 Pro Rescue. Thanks a lot - very good service!
Best regards,
Bernd
