I'm going to try again, but I can't seem to find any way to get verbosity in any logging and digging through the code of the script. I'm not really seeing anything obvious for why it doesn't appear to be launching into the tray

Hey, thanks for digging into this, you found a real bug and your instinct about the logging was exactly right: there was none. On Windows the bridge wrote everything to stdout, but it's launched through run_bridge.vbs with a hidden window, so every error, including full tracebacks from setup, went straight into the void. There was no log file on Windows at all, so there was genuinely nothing for you to find. As for why it never made it to the tray, it could die silently in a few places: • The script restarts itself inside its venv using os.execv, which on Windows builds the child command line without quoting. A single space in the path (a username with a space is enough) made it start the wrong thing and exit instantly. • The launcher called plain `python` via PATH. Without PATH set up that hits the Microsoft Store alias, and the VBS launcher reports no error at all when it fails. • The Python process could inherit the console from the .bat and get killed when that window closed. That's your "brief flash, then nothing". All of that is fixed now: • Everything is logged from the first line, setup failures included: %LOCALAPPDATA%\OSC HR Bridge\bridge.log • No more os.execv, and the bridge runs under pythonw.exe from the venv, so there's no console to inherit or lose. • First launch opens a visible setup window and keeps it open, so you can read any error. • If Python isn't found, you get a real message instead of silence. • Server thread crashes are logged too, a port conflict used to leave the tray icon looking perfectly healthy while nothing was listening. Could you grab a fresh download and try again? If it still doesn't show up, the log should now tell us exactly where it stops, just paste it here. Worth checking either way: Windows 11 hides new tray icons by default, so click the ^ arrow in the taskbar. There's an "Open log file" entry in the tray menu now too.

Hot damn, thank you so much for the explainer - planned on doing some work today so I will definitely grab the updated script and give it a shot/test the logging ^^

Glad I brought it up because running a random script from the internet and it "not doing anything" is usually a big red flag And could give people a big spook if they don't know how to read the scripts

is the osc functionality going to be rolled into the desktop app by any chance?
Community Member8/1/2026, 5:04:03 PM
