I am receiving the error, 'Cu Account User Is Invalid'


  • I am trying to activate my Unity license
  • A red cross appears next to the serial number and I receive the error, "Cu account user is invalid"


This is an error that occasionally appears if a user is activating with an account other than the purchasing account. It may appear if you have activated previously on the machine you are using.


To move forward with your activation, please delete any files found in these locations:

Windows users:


Mac users:

rm -rf ~/Library/Unity/Browser

More Information

If you are receiving this error and this solution does not allow the activation to go through, please contact us, preferably with your Log file, and we will investigate.
