Frequently Asked Questions

Is Adobe Acrobat X still supported by Adobe?

No, Adobe officially ended all technical and security support for Acrobat X on November 15, 2015. Continuing to use it may expose your system to security vulnerabilities.

What should I do if my Acrobat X serial number says 'Invalid'?

Ensure you are typing the 24-digit number exactly as it appears, without hyphens. Also, verify that you downloaded the exact version matching your license (e.g., you cannot use a Standard serial number for a Pro installer, or a Windows key for macOS).

Can I transfer my perpetual Acrobat X license to a new computer?

Yes. However, you must first deactivate the license on your old computer. Open Acrobat X on the old machine, click on the 'Help' menu, and select 'Deactivate' before installing and activating it on the new computer.
