Some users may find that .PDF files are not opening in Adobe and are instead opening in a web browser or another application.  To correct this, follow the instructions below.  


How to Set Adobe Acrobat as Default App for .PDF Files

  1. Click the Start button, then Settings.



  2. Click Apps

  3. Click Default Apps in the left margin.  Scroll down and click Set defaults by app.
  4. Choose Adobe Acrobat DC or Adobe Acrobat Pro depending on the version that you have and click Manage.  Ensure that Adobe Acrobat DC or Adobe Acrobat Pro is selected for .pdf files and NOT Microsoft Edge.  If an application other than Adobe Acrobat is set as the default, click on the app to select Adobe Acrobat.
