I can't install an F-Secure product on my Mac computer as it says after download: "The app can't be opened because it was not downloaded from Mac App Store"

Issue:

I tried to download and install an F-Secure product (SAFE, FREEDOME, ID PROTECTION) on my MacOS computer, but I receive an error message stating: "The app can't be opened because it was not downloaded from the App Store"

Resolution:

As per Apple's support article, you can allow downloaded apps from either App Store only or App Store and identified developers. Use the latter option and try downloading your F-Secure program again.
