To set a PDF viewer as the default on Windows
If when opening your SMS template, your Mac is defaulting to another PDF viewer (Not Adobe Reader) like the Preview App, you can change your default PDF reader to Adobe Reader by following these instructions:
If no other PDF viewer is installed, once Adobe Reader is installed, it becomes the default.
To set a preferred PDF viewer as the default:
Change the default program for opening PDFs to Adobe Acrobat Reader.
- Click the Windows Start button | Settings.
- Open Default Apps.
- Window 10 Professional build 1607
- Window 10 Professional build 1703
- Window 10 Professional build 1607
- Scroll to the bottom of the right column and click on Choose default apps by file type.
- Locate the file type you need to set a default app for (PDF for this example). To the right of this file type is the program that is currently set as default, or a box with a “+” sign in it that says Choose a default. Click on the program name or “+” box to assign a default app.
- When the Choose an app dialog box opens, click on the app you want to use (Adobe Acrobat Reader DC in this example) as the default. If no app is shown, click on Look for an app in the Store. This will open the Windows Store and you can then search by file type for a program.
- Test opening one of these files to make sure it uses the app you selected.
Root Cause:
Windows 10 comes with the Edge browser as the default reader for PDFs.
