How to Resolve Error message when opening the installer

Are you getting this error message when you try to open your downloaded installer?
“Microsoft Office 2016 can’t be opened because it is from an unidentified developer.”

Step 1: If you haven’t already, upgrade your device to the latest macOS

Step 2: Click on the Apple icon in the top left of your screen and open your Mac’s System Preferences. Select Security & Privacy and click the padlock in the bottom left to make changes. You’ll need to enter your Mac user password to continue. Now, under the option “Allow apps downloaded from:”, select Mac App Store and identified developers. Remember to close the padlock again before closing the window

Step 3: Ctrl+click (or right-click) the installer and click Open. You may get another notification saying “Microsoft Office 2016 is from an unidentified developer. Are you sure you want to open it?”. Click Open and it should start working

Step 4: If the installer’s still blocked, go back to Security & Privacy in System Preferences and change the “Allow apps downloaded from:” setting to Anywhere. Now try again.

  • Note: Mac’s GateKeeper function safeguards your computer by preventing harmful applications from being installed on your machine. While Microsoft is reliable, it’s a different company from Apple so its apps may still get blocked. However, there are many shareware applications on the internet from less reputable organizations that may carry viruses or risky software. So, make sure you change the Security & Privacy settings back to normal after you’ve installed your Office 2016 and always be careful with future downloads
