Can’t Run for the first time

[jreegan]

I’m on 10.15.7, tried to switch to 64 on 10.14 but the app had an X and the old app still worked so I went up 1 OS. Now 64 can be opened but when I do it says the following.

kJams 2 cannot be opened because of a problem. Check with the developer to make sure kJams 2 works with this version of macOS. You may need to reinstall the application. Be sure to install any available updates for the application and macOS

Any ideas what to do? I’ve never been able to run it for the first time.

Never mind, I see a reply on another about os11, standby and maybe it works!
