while dragging in the Python 3 Script component (or the ordinary Python Script component) it starts loading a few things, then it comes to “Installing Python Runtime” and it this point it always stalls. The Programm just freezes or closes instantly. I have tried a few things but non worked, so hopefully any of you could rescue me.
Welcome to the forum. This is usually the Python runtime download failing on the machine itself, often a network, proxy or SSL certificate issue rather than a Rhino bug. Can you run SystemInfo in the Rhino command line and post the results, plus the script editor logs? You can get to them with the _RhinoCodeLogs command (or Tools > Script > Editor), the lines about the runtime deploy are the ones we need. Also, are you behind a proxy, VPN or a corporate network?
Once you’ve grabbed the logs, lets try cleaning your python out: quit Rhino, delete the ~/.rhinocode folder (in Finder use Go > Go to Folder and enter ~/.rhinocode), then relaunch on a stable connection and let the runtime install again. Note the logs live inside that folder, so save them first. Thanks!
