Updating older slide shows for 64 bit

What procedure should I follow to upgrade older 32 bit slide shows before I upgrade to Catalina? Just upgraded to Fotomagico 5.6.10 and when opening some older 32 bit slide shows Fotomagico crashed. A few of the older shows were “recovered” but I can’t seem to get them to work or it can’t find the photos or audio to go with the show. Finally did find the media for one show but it only plays the audio and no photos. I’m still using Mojave 10.14.6 :frowning:
