How to Fix Cannot Open PDFs After Installing Adobe Acrobat Pro Trial
Question details
The user is unable to open any PDF files on their computer after installing a trial version of Adobe Acrobat Pro.
- Product
- Adobe Acrobat Pro
- Device & OS
- Windows
- Scenario
- Attempting to double-click and open a PDF document after recently installing a new PDF software trial.
- Observed behavior
- PDF files fail to open, likely due to broken file associations or trial account sign-in requirements.
Ensure you know which specific Adobe application you installed (Acrobat Pro vs. Acrobat Reader) and verify that your trial subscription is currently active.
Restore Default PDF File Associations
Manually reassigning your default PDF viewer resolves issues where Windows loses track of which application to use for opening PDFs.
Installing a new PDF application often modifies system registry keys for file associations. If the installation is incomplete or conflicts with existing software, double-clicking a PDF may result in an error or no action at all.
Locate any PDF file on your computer that refuses to open, right-click on the file icon, and hover your cursor over the 'Open with' option.
From the extended context menu, click on 'Choose another app' (or 'Choose default program' on older Windows versions) to open the application selection dialog.
Select Adobe Acrobat, Adobe Reader, or your preferred PDF application from the list. If it does not appear, scroll down and click 'More apps'.
Check the box at the bottom that says 'Always use this app to open .pdf files', then click 'OK' to apply the changes.
Sign In and Repair the Adobe Installation
Trial software may block access to files if the application is not properly authenticated or if the installation files were corrupted during download.

Frequently Asked Questions
Why did installing a trial change my PDF defaults?
When you install a new PDF application like Adobe Acrobat Pro, it typically registers itself as the default handler for PDF files automatically. If the trial setup is interrupted or the software requires a mandatory sign-in, it can leave those file associations in a broken state.
What happens to my PDFs when the Acrobat Pro trial expires?
Your PDF files are completely safe and will not be deleted. However, when the trial expires, you will lose access to Acrobat Pro's premium editing features. You will need to switch your default viewer back to a free reader, such as WPS Office or Adobe Acrobat Reader, to continue opening them.
Can I open PDFs without an active Adobe subscription?
Yes. PDF is a universal file format. You can view PDFs using modern web browsers (like Google Chrome or Microsoft Edge), built-in system viewers, or free specialized software like WPS Office.
