I've installed it on my PC without any problem. Now I'm in my parents home and I'm trying to install it on my mom's laptop. I tried with other mods, now I tried on clean KSP install, nothing happens. I unpack it to GameData, so the DLL is in GameData\MagicSmokeIndustries\Plugins\InfernalRobotics.dll After starting KSP it loads stuff from MagicSmokeIndustries, but there are no parts in Sadbox and in Career. :/ EDIT: Nevermind, I had to put Toolbar directory in GameData, I didn't know it was necessary.
