Hi @longphx. Welcome to the community and to zrok (and OpenZiti).
do you know if your windows 7 device is 32 or 64 bit? it looks like maybe 32 bit? I don't have a windows 7 device to test zrok with, myself. unfortunately Windows 7 is end of life. We don't make builds for nor test on OS's that can't receive security updates. I don't know if there's much that can be done here
