Cannot execute: required file not found

Hi there,
I wonder if i did something wrong or if slide isn't working anymore. I'm trying it on a Raspy 5 and followed the instructions on https://opensource.com/article/19/2/wifi-picture-frame-raspberry-pi. I always get the problem that if I try to start the slideshow it says:
-bash /usr/bin/slide: cannot execute: required foel not found.
Any suggestions on this?

OK, I think I have found the problem. It seems that slide unfortunately does not work with the 64bit version of Raspbian. After switching to the 32bit version it seems to work.
