Hello,

I moved 3 virtual machines from one laptop to another, by exported the machines to OVA.

Windows 7 (VIDA 2014d)
I could only get 1920 x 1080 with this machine after installing Guest Additions.
When I shut down, it tells me about "Windows - Bad Image" warning, I click "OK" and it shuts down.

Windows 10 (Vida 2014d)
After installing Guest Additions twice, I only get up to 1344 x 665.
I cannot shut it down completely, I have to use Task Manager to close it.
After restarting, I still do not the the high resolution.

Windows 10 (Vida 2014d)
After installing Guest Additions, the highest resolution I get is 1280 x 720.

Then I copied the machines with it's folders, pasted them in the same folder as in the source, used the green H to add (register) the machines, this time, none of the machine will open.

In the source laptop, all works well.

I wish I could find a Vida OVA file to use. The links I found and not working.

Cheers.
