FAQ:Fritzing Freezes on Start

Q: When I start Fritzing, the progress bar goes part way across then stops. Fritzing does not finish loading.

After being installed, when Fritzing is first run, it checks github for parts library updates, and appears to hang. If Fritzing is aborted during that update, the local database can be corrupted, and further attempts to run Fritzing will fail. Uninstalling and reinstalling Fritzing will not fix the problem either. The local database is not removed by the uninstall, and the new install will attempt use the existing bad database.

There is an easy fix however:

If you don't have any part or sketch files you want to keep, you can just delete the bad database folder and configuration files. Fritzing will recreate them the next time it is run. No reinstall needed.

Windows

c:\Users\username\My Documents\Fritzing
c:\users\username\AppData\Fritzing\roaming\Fritzing

AppData is a hidden directory, so you need to enable hidden directories in explorer to view and delete that file.

Mac

/Users/username/Documents/Fritzing/parts
~/.config/Fritzing

Linux

~/Documents/Fritzing/parts
~/.config/Fritzing

When starting up Fritzing after removing the database and configuration file, let it run. That initial parts library update can take some time. Once updated, later runs start much faster.
