I just updated from Windows 7 to Windows 10 and VMplayer 7.1.2 build-2780323 running Windows XP Mode gives the following message "This system is not allowed to run "Windows XP Mode". The virtual machine will now power off.". It was running fine under Windows 7. I tried installing VMplayer again and it gives the same message. I tried Ubuntu 12.04 Tools in VMplayer under Windows 10 and it ran ok as it did under Windows 7.
Any ideas what I need to do other than drop back to Windows 7?
