Download the official Adobe Acrobat Cleaner Tool from Adobe's website. Run the utility to remove all leftover registry keys and licensing files associated with the Pro trial.

Frequently Asked Questions
Why does my Acrobat Standard serial number say invalid?
Acrobat Standard serial numbers cannot activate Acrobat Pro. If a Pro trial is still lingering on your system, the software will reject the Standard key. You must completely wipe the Pro version using the Adobe Cleaner Tool.
How can I tell if my Acrobat 2017 copy is counterfeit?
Because Adobe has discontinued Acrobat 2017, many heavily discounted copies sold by unofficial third-party vendors are counterfeit. If your serial number is consistently rejected or revoked, verify it directly with Adobe support.
What is the Adobe Acrobat Cleaner Tool?
It is a free official utility provided by Adobe designed to wipe leftover registry entries, preferences, and installation files from previous Acrobat installations, fixing conflicts caused by expired trials.
Can I downgrade from Acrobat Pro to Standard without uninstalling?
No, you cannot directly downgrade an expired Pro trial to the Standard edition. You must fully uninstall the Pro version and perform a fresh installation using the correct Standard media.
