I have the same problem.
After installing the demolicencse i need to reboot, and after that the device will autoswitchoff after some seconds, i even cant look whats wrong, because of this autoshutdown. I barely can see that "license expires" for a half second, before the device is shutting down.
Even if i dont use any license i cant use the Routeros. On second reboot or reset the license is expired. Without ever logged in to the routerOS.
Should use CHR version in virtual environments, sounds like you are using the 32 bit version meant for dedicated hardware
