Calibre doesn't start
 

The application shows up in the task manager.

I had my library on a network drive (yeah, I didn't read the FAQ beforehand). The IP changed and when it started up it said it couldn't find it and asked me to point it to the new directory. I did so and then it froze.

I killed it and tried to restart it but the same thing keeps happening.

I was thinking that maybe I need to edit the config files by hand or something. But I'm not sure where. I can't find where they are stored. I've searched but I've only found that if you open the program you can click in the preferences and it will open the location.

Ok, I did a search for the network path in all directories titled Calibre in both program files and app data. I replaced the old network path with the new network path. no dice.

I uninstalled and reinstalled. Copied my network drive to my local machine intending to point the fresh install there. Calibre still does not start.

Uninstall should be a fresh slate.

Calibre's uninstall is not a clean slate. Quite a bit is left behind so you can re-install without losing settings, plugins, libraries, etc. The last time I tried a complete uninstall of calibre under Windows, I removed the calibre2 directory from Program Files, the calibre-cache directory from AppData\Local and the calibre directory from AppData\Roaming. I also exported my libraries to an external HD and deleted them but that was likely overkill.

If you want to start calibre with a particualr library path simply run it from the command prompt with

calibre --with-library "C:/path/to/library/folder"

That did it.

Thanks! I'll remember that next time.
