title: Incompatible Protocol Version Warning
category: troubleshooting
---

This warning happens when your LBRY browser did not install with the proper version of the software used to communicate with the LBRY network.

The most likely cause of this error is an old version was running during the install process.  This can usually be fixed by re-running the LBRY setup files after ensuring that no LBRY processes are running.

### How to Fix

1. Click `Quit Daemon` in the LBRY app to kill the LBRY network process. 
1. Restart your PC or ensure that any processes with "lbry" in the name are not running. 
1. [Download](https://github.com/lbryio/lbry-app/releases) and re-install the latest version of LBRY. 
1. Start LBRY
