Generally this issue occurs when activation_request.txt/activation_response.txt  file get corrupted while moving from one PC to another.

 

Have you compressed or zipped the files while moving from one PC to another ? If yes, I recommend opening a support ticket with the Kepware Technical Support team. Here is a link to the my kepware login page where a ticket can submitted:
