You do not have permission to enter a license key. Try again using the system administrator account.

OK

Answer 1

You maybe saw a fake solution on the Internet like this:

1. Run CMD as administrator
2. Enter the location of file 'vmware-vmx.exe' (like: D:\Program Files\VMware Workstation\x64)
3. Type command as this:
   • VMware Workstation\x64>vmware-vmx --new -sn AG31K-0GD5P-08ERP-TEQZV-WG09A
4. Nothing happened, the error is the same

AppNee tells you the root cause: The VMware Authorization Service is not running. How to make it running? The easiest way is - reinstall your VMware Workstation (then it can register this service and make it run), or you can register this service instead. Trust me, this is the only working method to solve this problem efficiently and directly.
