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

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 only way is - reinstall your VMware Workstation (then it can register this service and make it run). Trust me, this is the only working method to solve this problem efficiently and directly.
