Repair the Acrobat Installation
Use the built-in repair tool to fix corrupted application files that may be causing graphical glitches and cut-off dialog boxes.
Acrobat includes an automatic repair feature that scans for missing or damaged installation files. Running this tool is the quickest way to resolve unexpected interface bugs.
Launch the Adobe Acrobat application on your computer.
Navigate to the top menu bar and click on the 'Help' tab.
Select 'Repair Installation' from the drop-down menu and follow the on-screen prompts to complete the process.
Once the repair is finished, restart Adobe Acrobat to check if the dialog buttons display properly.

Adjust Display Scaling and Resolution Settings
High display scaling or low screen resolution can cause Acrobat dialog boxes to overflow and hide buttons.
Uninstall and Reinstall Acrobat
If repairing and adjusting display settings fail, a clean installation using the latest installer can resolve deep software conflicts.

Frequently Asked Questions
Why are the bottoms of my PDF dialog boxes cut off?
Dialog boxes often get cut off when your system's display scaling is set too high (such as 150% or more) or your screen resolution is too low. Adjusting your Windows display scale to 100% or 125% usually brings the hidden buttons back into view.
Is there a keyboard shortcut to trigger the missing 'Add' or 'OK' button?
Yes. If a dialog box is cut off and you cannot see the 'OK', 'Add', or 'Submit' button, you can often press the 'Enter' key on your keyboard to trigger the default primary action. To close the dialog without saving, press the 'Esc' key.
Does reinstalling Adobe Acrobat delete my PDF files?
No, uninstalling and reinstalling the application only removes the software program files from your system. Your personal PDF documents, folders, and saved data remain completely safe on your hard drive.
How do I add custom PDF page sizes without using Acrobat?
You can use alternative PDF editors like WPS Office, or set custom page sizes directly through your system's virtual printer settings. Navigate to 'Devices and Printers', select your 'Print to PDF' driver properties, and define a custom paper size there.
