"The process for the desktop protocol died unexpectedly"


I have installed a portable version of VirtualBox on my flash and I am able to run both Whonix gateway & the workstation.

However as soon as I try open any application it crashes and tells me

“The process for the desktop protocol died unexpectedly”

I found a similar question on VirtualBox website but no one had an answer for them.

It is quite frustrating


On the host or within the VM?

On the host → not a Whonix question. That would be independent of Whonix and a general VirtualBox / Windows question as per Free Support for Whonix ™.
