So i have my Wow.exe working fine and dandy, but the problem is my brothers exe. He launches the WoW.exe that he is suppose to and it instead of launching Wotlk it launches the battle.net WoW, launching Warlord of Draenor. Any help here? Thank you ahead of time!

Reason: Worded kind of wrong
If it's WoD then it has updated. If he has battle.net client installed it might have detected WoW folder and updated it. Also logging in with email can update wotlk client but it usually stops at Cata not WoD.
If it has updated he will have to download it again. Also if it was updated by battle.net client then check its settings to make sure it doesn't happen again.
It might be "Scan for Blizzard games in the background every time Battle.net launches" under "Game Install/Update". Check the other settings there to see if it has added the game and if you can remove it also.
