Product activation failed - Sage 50 Accounting 2019

SUGGESTED

Hello everyone,
Thank you for your help.

I had to reinstall Sage 50 on a laptop because of some problems, but when it reinstalled it asks me to activate the product, normally I give it Activate online and it stays.
But on this computer I get the error:
"There was a problem generating the Pervasive authorization key for Sage 50. Please call Sage Technical Support."

And I don't know what else to do, I tried reinstalling Pervasive, disabling the firewall, and nothing.

If anyone knows how to fix this I would really appreciate it.

Happy day to you,
