32-bit app Pop-Up message on macOS 10.13.4 (High Sierra)

If you're seeing this warning similar to this, you are likely running a 32-bit app on macOS 10.13.4 (High Sierra).

At the 2017 Worldwide Developers Conference, Apple announced that High Sierra would be “the final macOS release to support 32-bit apps without compromises.”  Read the full support KB article from Apple here.
