Hello,
please use the manual authorization for pgp command line.
Please save the manual authorization string to a text file and specify the file (e.g. auth_file.txt) while activating the license:
pgp --license-authorize --license-name "My Name" --license-organization "Corporate Synergies Group, Inc" --license-number "xxx-xxx-xxxx-xxxx-xxxx" --license-email "my.email@mail.com" --force auth_file.txt
If you do not have the manual authorization string, please contact Symantec Customer Care: http://customercare.symantec.com/
