How to Fix Adobe Acrobat 2017 Keeps Prompting for a PDF Application
Question details
Windows continuously prompts the user to select an application when opening PDF files, despite Adobe Acrobat 2017 being set as the default.

- Product
- Adobe Acrobat 2017
- Device & OS
- Windows
- Scenario
- Opening a PDF file from Windows File Explorer or the desktop.
- Observed behavior
- A 'How do you want to open this file?' dialog box appears every time a PDF is opened, ignoring previous default application settings.
Ensure you have administrator privileges on your Windows computer, as modifying default file associations and registry settings may require admin rights.
Reassign the Default PDF Application via File Explorer
Manually force Windows to remember your default PDF viewer choice using the 'Open with' context menu.
Often, a simple reset of the file association directly from the file itself will override any conflicting Windows settings.
Find any PDF document stored on your Windows desktop or within File Explorer and right-click on it.
Hover over 'Open with' in the context menu, then click 'Choose another app' from the extended list.
Select Adobe Acrobat 2017 (or Adobe Reader) from the list of available applications.
Check the box at the bottom that says 'Always use this app to open .pdf files', then click 'OK'.

Configure Default Apps in Windows Settings
If the context menu method fails, force the file association through the main Windows Settings panel.
Install the Latest Adobe Acrobat Updates
Bugs in older versions of Acrobat can cause Windows registry conflicts. Updating the software can resolve persistent prompt issues.
Use WPS Office as Your Reliable Default PDF Reader
Tired of persistent application prompts and registry conflicts? WPS Office includes a built-in, highly stable PDF reader and editor that seamlessly integrates with Windows, providing a hassle-free document viewing experience without constant interruptions.
- 1. Download and Install: Download WPS Office from the official website and complete the straightforward installation process.
- 2. Open WPS PDF: Launch WPS Office, click on 'PDF' in the main dashboard, and open your document.
- 3. Set as Default: When prompted by WPS Office upon your first PDF opening, click 'Set as Default' to let WPS handle all .pdf files permanently and cleanly.

Frequently Asked Questions
Why does Windows keep asking me how to open a file when I already set a default?
This usually happens due to a Windows registry glitch, a recent Windows update resetting your file associations, or multiple PDF programs fighting for default status. Re-applying the default setting via the 'Choose another app' menu typically resolves the conflict.
Can I use the Windows Control Panel to fix PDF file associations?
Yes. If the modern Settings app fails, you can press Windows + R, type 'control', and navigate to Default Programs > Associate a file type or protocol with a program. Locate the .pdf extension and assign it to your preferred PDF reader.
Will reinstalling Adobe Acrobat fix the persistent prompt?
If resetting the file association in Windows settings and updating the software do not work, a clean reinstallation of Adobe Acrobat can fix corrupted registry keys that are causing the continuous prompting.
