NOTE: You will need to have a PDF reader downloaded on your computer and set to your default PDF reader in order for this process to work correctly.
Step 1: Navigate to Chrome and click on the three vertical dots at the top right corner.
Step 2: A drop down menu will appear. Click on Settings.
Step 3: Scroll to the bottom of the Settings page and click on "Advanced" to open the advanced options. Under Privacy and Security, click on Content settings to open that section.
Step 4: With Content Settings open, scroll down and click on PDF Documents. You will see an option that says "Download PDF files instead of automatically opening them in Chrome". Click the toggle to turn it on. You should now be able to view documents in your downloaded PDF reader.
