32 bit to 64 bit

Getting Started

My system is MacOS 10.15.4
I have several apps I wrote with RealBasic for a previous Mac operating systems. How can I convert them from 32 bit to 64 bit? Just opening them in XOJO (2019 version 2.1) does not work. If I click “build” and try to run the result, I am told to contact the “developer”.

I have solved the problem myself. Click your selected build setting and you have the option to choose 32 bits or 64 bits.

You better use Xojo 2019r3.1 (if you can)… there was so many changes vs r2.1 !
