How do I use this to fix my launcher?
Download the Launcher-LoneWolfFix.zip
below. Unzip it and copy the files to your Steam\steamapps\common\Homeworld\HWLauncher
, override the files there.
Note: this patch makes the launcher not crash when it cannot get correct response from Gearbox's account authorization server. However, unless Gearbox fix their server at their side, this patch won't enable you to play multiplayer game through Gearbox's server. LAN multiplayer is not affected by this, though.
