This is a generic warning only. You have to do nothing, 32-bit apps continue to work on High Sierra & Mojave.

In the future release of macOS 10.15, applications will have to be 64-bit. App developers will issue updated apps if they want their apps to work on these future releases.

32-bit app compatibility with macOS High Sierra 10.13 ... - Apple Support
