When it comes to the cross-platform video chatting apps, Skype tops the list without any doubt. Although Windows 10 comes with pre-installed Skype, you may need to download its installer to install the app. I recently received this error when I downloaded its setup and ran it to update Skype.
Installing Skype failed; code 1603, A fatal error occurred during installation.
