Question: program doesn't show up in launch pad
I installed an app from the internet via a dmg-file on my Mac mini running macOS High Sierra, Version 10.13.3. The app shows up in my programs folder, I can start it from there and it works perfectly but it doesn't show up in Launch Pad.
Any ideas what could be the reason for that and how to fix it?
Thanks in advance
Mac mini, macOS High Sierra (10.13.3)
