Re: Issue with NEST Live Media 2.20
by Steffen Graber 27 Aug '20

27 Aug '20

Hi Maryada I just tested the VM with Windows 10 Home (Version 1903) and with Virtualbox 6.12. No problems at startup. The network does not seem to start in your installation. If not done yet I would first delete the VM completely and reinstall it. Then deactivate the network in the settings of the VM and restart it again. Hope this helps.

Hi, I am trying to import Live Media 2.20 however the VM virtualbox is always get stuck immediately as it starts (see attachment). I also tried to import the 2.18 version just to be sure if it's an issue on my side. However, that's working perfectly fine. Is there an additional requirement that I might be missing? -- Thanks and Regards *Maryada*
