Windows binaries require the Microsoft Visual C++ Redistributable:
https://aka.ms/vs/17/release/vc_redist.x86.exe (32 bit)
https://aka.ms/vs/17/release/vc_redist.x64.exe (64 bit)

Linux AppImage requires at least glibc 2.27. Check with ldd --version if in doubt (any recent Linux distribution should easily satisfy this). FUSE must be enabled and available (see https://docs.appimage.org/user-guide/troubleshooting/fuse.html)
