I install Backup Exec 21.4 on Windows Server 2022. The server is in a n Active Directory Domain.
During the installation, one step is to input the password:
the default user name is : Admin, the default domain is:NT, I input the password and click the next, it prompts: unable to authenticate with the user and password information given for NT\Admin.
The following is some part of the installation log:

I had installed NetBackup on this server and uninstalled it.
Service account exists may the prolem, but I don't know how to deal with it.
