This might be a really ugly solution. But GE-Proton10-12 can install all installation files individually with help of steam. Issue is that filemaker program itself cant find the dependencies even if they are technically installed. But they are installed as their own “games” Still, step in some direction.
I suppose one could move the files from .local/share/Steam/steamapps/compatdata/2333569529/pfx/drive_c/Program Files/FileMaker/FileMaker Pro 19/ to .wine instead and hope for the best. And the same with the other programs that are the dependencies
