How to Fix an Acrobat Encryption Dialog Box That Is Too Large
Question details
The user is unable to complete PDF security settings because the encryption dialog box in Acrobat DC is too large for the screen, hiding the bottom controls.

- Product
- Adobe Acrobat DC
- Device & OS
- Windows 10
- Scenario
- Attempting to encrypt a PDF document using Encrypt with Password or Encrypt with Certificate.
- Observed behavior
- The encryption dialog box extends beyond the edges of the Windows 10 screen, obscuring the bottom controls like the OK or Apply buttons, and preventing the user from finalizing the settings.
Before troubleshooting display settings, try pressing the 'Enter' key on your keyboard after filling in your encryption details, as this will often trigger the hidden 'OK' button and apply your settings.
Adjust Windows Display Scaling and Resolution
Lowering your display scaling or increasing resolution can help fit the oversized Acrobat dialog box onto your screen.
Windows 10 includes built-in display scaling to make text and apps easier to read, but setting it too high on smaller screens can cause large application windows to overflow the screen boundaries.
Right-click on an empty space on your Windows 10 desktop and select 'Display settings' from the context menu.
Scroll down to the 'Scale and layout' section and change the size of text, apps, and other items to '100% (Recommended)' if it is currently set higher.
If the scaling is already at 100%, look at the 'Display resolution' dropdown and select a higher resolution to provide more screen real estate.
Close and reopen Adobe Acrobat DC, then access the encryption dialog box again to see if the bottom controls are now visible.

Move the Dialog Box Using Keyboard Shortcuts
Use Windows keyboard shortcuts to manually move the dialog box up so the bottom controls become visible.
Update Adobe Acrobat DC
Interface scaling bugs are often patched in software updates. Ensure your Acrobat DC is running the latest version.
