As Squall has said, there is no launcher for the Steam version.
 
	 
 
 
	You mean this mod? The K2CP mod? That Community Patch?
 
	 
 
 
	The K1CP should be installed first for Kotor I mods only, the same does not apply to K2CP - the reason for this will be listed down below.
 
	 
 
 
	K1CP is to be installed first for Kotor I, followed by RC-K1CP the Kotor I restored content mod for that game.
 
	TSLRCM is to be installed first for Kotor II, followed by K2CP assuming you aren't using M4-78EP.
 
	 
 
	The reason TSLRCM is installed first is because it was released first, its installer does not use a combability installer like TSLPatcher or HoloPatcher that'll merge conflicting files together. Instead, TSLRCM's installer just copies all of the files into the right places to install the mod.
 
	 
 
	TSLRCM is massive and it changes a lot of things so it wouldn't be feasible to have a compatibility installer. It both restores cut content and fixes hundreds of bugs. Modern mods get around this by making you, the player, install TSLRCM first and our mods afterwards. We make our mods with the objective of being compatible with TSLRCM and K2CP is no different.
 
	 
 
 
	You install TSLRCM, you launch the game, and you see if the Kotor II logo has been replaced with a new Kotor II logo that says TSLRCM 1.8.6 in-game.
 
	 
 
	That's how you check on Steam.
