Frequently Asked Questions

Why does Acrobat 9 Pro say it cannot connect to the activation server?

Can I still call the support number shown in the Acrobat 9 error window?

No, the support phone numbers hardcoded into older versions of the software are no longer in service. You must use the official website to contact modern customer care.

Are third-party Acrobat activation services safe to use?

No. Third-party services or keygens claiming to bypass activation are usually unauthorized and carry a high risk of installing malware or viruses on your system. Always seek official support.
