Instructions
Step 1
Open Adobe Reader, select "Help" and "Check for Updates" from above.
For some time the program will establish a connection with the server, after which it will either inform you about the absence of updates, or offer to download them.
In the first case, click "Finish" - at the moment you have the latest version installed.
In the second, press the "Download" button and, after waiting for a notification in the tray, click on it.
Step 2
A window appears notifying that the updates have been downloaded successfully. Click the "Install" button.
Updates will be installed for about a minute, and after it is complete, the program will prompt you to restart your computer.
