WTware RDP client

This is erroring out when I go to install on Virtualbox.

I've removed the virtual hard drive and attempted it again.

Whenever I go to update WTWare, I get this error... I also get this error when I go to install on a fresh machine.

yes, in my opinion

Unfortunately RDP is not an option with our limited resources. I am using UltraVNC Server, as far as the client goes, whatever is built into WTWare.

So, after several hours my virtual machine WTWare thin client, and my 2 Raspberry Pi's shows "I'm Tired."

The logs are as follows:

Raspberry Pi 2: https://pastebin.com/gYyqL2tK


Any help would be appreciated.

Thanks in advance!
