Nothing happens on double-click
Look for a leftover process in Task Manager, end it, and retry. If nothing changes, try a minimal profile.
Troubleshooting
Client will not start: troubleshooting order
Check source and architecture, port conflicts, profile format, permissions, and logs, in that order.

Who it is for
Users whose client does nothing on double-click, errors out at launch, or hangs while loading a profile.
Prerequisites
- The client name and version
- The error text or a log excerpt
- Where the installer came from
Troubleshooting steps
- 1
Confirm the installer source and architecture first; that is the most common cause.
- 2
Check for a second instance still running, including one hidden in the tray.
- 3
Check whether the port is taken; default ports often collide with other proxy tools.
- 4
Start with a minimal profile. If it launches, the problem is in your original profile.
- 5
Finally read the log and search official issues using the error keywords.
Common issues
Profile parse error
YAML indentation or a bad field. Compare against an official example instead of editing unknown keys.
Next step
Confirm the version and supported platform instead of staying on a mismatched build.
