I restarted my PC, went to run my Windows 7 VM and I got this error.
So far I've re-installed VMware but still getting this error.
Any help would be greatly appreciated
Hello,
You could try the following, it seems to have helped others:
power off the vm
open cmd prompt as administratir
run the following:
net start vmx86
net start hcmon
net start vmauthdservice
power on vm
try opening console

Are you able to collect logs and attach to this thread?
Instructions: VMware Knowledge Base
Please include the VM logs, there will be an option to select logs for this specific VM when prompted.
I had identical symptoms after installing 14.1.1, build 7528167. Rebooting the host made the problem go away.
