Why do I get the message "Capture Button Serial Port Unavailable"?
Harmless if you use Auto Capture. If you use the button, its COM port wasn't found: plug the button in before opening FinishLynx and select its port in File | Options | General.
"Capture button serial port unavailable; keyboard capture will be used." This common message can appear when FinishLynx starts. If you use Auto Capture and not the capture button, no action is needed and you can run your meet as planned.
If you do use the capture button, the COM port it is on was not found. Check that the USB adapter is plugged in before FinishLynx opens and that its COM port is selected under File | Options | General. See My USB adapter is installed but the COM port isn't listed, or Capture button not working in Troubleshoot.

- My USB adapter is installed, but the COM port isn't listed in the dropdown. — FinishLynx reads COM ports when it opens, so plug the adapter in first and restart FinishLynx. If Device Manager shows a warning on it, reinstall its driver; current versions already list every port type (TypeMask -1).
- Why doesn't the computer recognize the USB adapter (COM ports)? — Usually the driver was never installed, or an old one was carried over by a Windows update. Install the right driver for your adapter (FTDI for the USB button, ATEN UC232A for the older adapter), then plug it in.
- Can I use the keyboard to toggle capture? — Yes, as a backup: set the capture button to Keyboard in File | Options | General and tap the spacebar on and off. It's easy to lose track of, so the button is better.
