Adobe Acrobat Reader DC trava ao clicar em Assinar

Hello @moesio_reis

I hope you are doing well. We are sorry for the trouble and for the delayed response.

Could you please share more details about the issue? Is Acrobat crashing when you try to add a digital signature? Is it occurring with all the PDFs or with a specific PDF? Are you on a Mac or a Windows machine, and what is the version? 

Please ensure you have the latest version of Acrobat installed on the machine: 25.001.20630, Planned update, Aug 18, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and try again.

Delete Signature Cache Files. Corrupted signature cache files can cause crashes. Try deleting these: 

Delete files like:

acrobat_fss_signature_initials
acrobat_fss_signature_initialsi
acrobat_fss_signature_initialsk

Recreate the Digital Signature, and try again.

Turn Off Protected Mode (Temporarily). Open Menu→ Preferences → Enhanced Security. Uncheck “Enable Protected Mode at startup” and “Enhanced Security”, then click OK and reboot. After testing, re-enable them for security.

Clean Installation (If Needed). If the issue persists, uninstall Acrobat and use Adobe’s Cleaner Tool to remove the remaining traces. Reinstall Acrobat. 

Let us know how it goes.

Thanks,

Anand Sri.
