Launchbox not starting.


Recommended Posts

Hi there. I am finishing up a launchbox build on a removable SSD for a friend. Working on it today and all of a sudden the app won't launch anymore. It was working one moment, then after a game the launcher just spins. I have restarted, there are no issues with antivirus.

Need to know how to download/install a new copy of the app without having to copy out or move the 2tb game folder I spent the last 3 months organizing. I clicked the uninstall option and it asks me if I want to delete all the components. I definitely do not.

How to fix.

Thanks.

LB keeps copies of installer files in the ...\LaunchBox\Updates folder so you can rerun the installer from there as well as try an older version if think that is the issue.  It will over write and/or update any files that were missing/corrupted but doesn't touch your games, images, and metadata folders (i.e., your specific setup). 

It does sound to me like an antivirus issue if you double click and then nothing happens.  Some AVs would trigger due to the way more recent versions of LB running from the ..\\Launchbox\Core folder (symlinks).  So I would make sure the LB folder is excluded from your antivirus before rerunning the installer.

I finally have some time to work on this tonight.

I have the updates folder open and I am looking at a .exe from the day my install got corrupted. I should run this and have it install into the existing folder? 

From there it will overwrite ONLY the corrupted files leaving my games, themes and everything else untouched? That sounds too good to be true.

I copying the corrupted install to make a backup of the game folder just in case something goes wrong. I think I would have to jump off a bridge if I had to reconfigure this thing again.

As I said, if you re-run the installer it will not touch the games, themes folders other than reinstalling the files LB needs to run for whatever version you are launching from the updates folder.  Also LB keeps backups of the XML files (its settings, data, configuration) in the Launchbox\Backups folder.  Go to Tools, File Management, and Data Backup and you can force a backup before you do anything.
