I just downloaded the new Beta ICCup Game Launcher v5.1, and even though I am pointing it to the wc3 game path, it will not start the game.

If I use the ICCup Launcher v1.6, it does launch the game, but it seems I can't find that many Dota games on it... please help

Good day to you, dear user! I advice you to reinstall the BETA iCCup Launcher and try to point the War3 path again! Usually this method helps, but it may also be due to an update. Try to update to the latest version. If it does not help, you can just contact with Technical Support department and clearly explain them your problem and they will help you to solve the issue!
