Having the latest version of your software can be a good thing because in most cases, the newer software will contain the latest security updates for that time as well as any bug fixes for issues in previous versions. Adobe is an example of software you should periodically reinstall.
Sometimes the software we purchase isn’t ever updated until a new version is released for sale. Other software goes through numerous updates between version releases, like Adobe Reader and Flash. I recommend you remove and reinstall Adobe Reader on your Macs, as well as reinstalling the Adobe plug-ins. On a PC, don’t remove Adobe Flash, but do reinstall Adobe Reader if it has been a while since you did this.
If you are running macOS Sierra, open Finder and then open Applications. Locate Adobe Reader and then move that icon to the trash. You may need to give permission by entering your Apple ID and Password.
Next, open Safari and then select Safari at the top and then Preferences. Select the Security tab and then select the Plug-in Settings button. In the window that opens, highlight the Adobe plug-ins one at a time, and select the (-) minus sign at the bottom of the box to remove the plug-in. This removes the plug-in, but it will be reinstalled when you go to a website requiring it. Remove all plug-ins and then select Done at the bottom.
To reinstall Adobe Reader on your Mac, go to Adobe.com, select the three-lined icon at the top-right, then scroll to the bottom and select Acrobat Reader DC on the left. Select the Download now button and it should begin shortly. Once it has downloaded, select the down arrow in the circle icon at the top-right of Safari and then you will need to double-click the “AcroRdrDC” file to begin the installation. Double-click the “AcroRdrDC” package file to continue. Follow the remaining instructions to install. Once installed, you can move the installer to the trash and close all the windows.
If you are running a PC, open your control panel and then click “Programs and Features.” Click Adobe Reader and then click “Uninstall” at the top of the list. Click “Yes” to give your system permission to continue. Follow the remaining instructions to uninstall Adobe Reader and then restart your computer.
To reinstall Adobe Reader to your PC, go to Adobe.com and at the top-right, click the three-lined Menu icon. Next, at the bottom, click “Acrobat Reader DC.” Follow the remaining instructions to finish the installation.
Installing a fresh copy of your software can give you added security, but it can also help your computer’s performance.
