Hi! There's a long list, but it's difficult to tell if all those would apply and actually work: - Upgrade the Linux Kernel This one I tested in a VM and it worked. I got the same error about the library not found in that VM while still running the default 3.x kernel. After Upgrading to latest mainline kernel 5.12, the OpenSCAD Snap runs fine. - AppImage probably will not work with CentOS7 being based on ancient libs - Flatpak might be an option, supposedly it's installed on CentOS7 by default - Compile from source, as some of the libraries seem to be missing in the default CentOS package source, that could be a bit more than just compiling OpenSCAD itself - Upgrade to CentOS8, I don't know if that would make a difference, but it might allow the AppImage to run and bring a new kernel to make things work ciao, Torsten.

Thanks for the quick response  and the great suggestions. I removed the snap version and installed the stable version from flathub. I am back in business! Version from Flatpak is OpenSCAD <https://www.openscad.org/> version 2021.01 I am wondering if I actually started my OpenScad journey with the Flatpak version originally. Still curious about why the snap version doesn't work but relieved that I can get back to designing things. As a programmer, I find the OpenScad way of doing design to be very easy. I am sure that I have a lot to learn. The group is very helpful. I am running Linux 3.10.0-1160.25.1.el7.x86_64 on x86_64 I am not sure that I am ready to move to Centos 8. The relationship between RedHat, Fedora and Centos seem to be in a state of flux with Centos going from a slightly behind version of RedHat which was pretty stable to something more like a testbed for RedHat - a Fedora light? I have moved through the versions of Centos for the past 20 years but am rethinking my choice of OS. I am also looking at changing the hardware to ARM (Raspberry Pis) both for servers and workstations so that seems to require a rethink of the Linux architecture.
