The suggestion from SyncTrayzor access problems (latest downloadable from the site) remains the same:)
Copy syncthing.exe from Syncthing windows-amd64-v1.26.1
Paste it in C:\Users\<You>\AppData\Roaming\SyncTrayzor
As described in GitHub - canton7/SyncTrayzor: Windows tray utility / filesystem watcher / launcher for Syncthing
The problem is that SyncTrayzor hasn’t been updated for over two years and defaultly ships with an old version of Syncthing. So when you actually first run 1.26.1, it creates a Syncthing configuration for that version…but that’s not directly compatible with the old version of Syncthing which SyncTrayzor uses/ships with.
So, really, if you want the icon, notifications and idk what else for reasons one has for using the wrapper then do the above. Otherwise you can just use syncthing.exe directly (your initial approach) and use the `http://127.0.0.1:8384’ url to manage it.
