Not really sure what you mean.
Where and how did that error message pop up ?
If you were installing the CREATE editor did you agree to any pop up boxes etc ?
There should be at least two and possibly three boxes that pop up.
Once for a certificate which must be installed.
Another for drivers for each particular board you connect to CREATE
Possibly a third for firewall permissions.
If you dont agree to the pop ups then you wont be able to use CREATE.
