Hi drEskimo,


It could be that the application is 32-bit.


With MacOS Catalina, Apple drops support for 32-bit applications for 64-bit only. See 32-bit app compatibility article if you wish.


I would check with the developer to see if they have a 64-bit version available.


I also did a little research and found an article, switching to 64 bit version from 32 bit version that should help you.


I hope this helps.
