Hello, if you are using Professional Edition for the first time, you need to set a login password to activate the certificate. The password is composed of 6-8 digits of pure numbers or letters or a combination of numbers and letters. You can download the professional installation program here, open the login interface after the installation, and connect UKEY. On the login interface, you can see "Set User Password" and "Confirm User Password". After you set the password, click Login.

if you have any other questions, I suggest you consult online customer service /cmu/icslogin.aspx? from=B& logincmu=。 Thank you for your attention and support!
