Error: When starting Warcraft III Frozen Throne you get an error: “Sorry, Warcraft III could not be opened.”
Download patch 1.21b
Run Warcraft III Frozen Throne
Update with Battle.net
So today I broke down and bought the Warcraft Battle Chest. I was trying to find a game my Macbook Air could play 😉 Anyways, I install and download the newest updates from the Blizzard FTP. I start playing Warcraft and it was as fun as I remembered. I then want to play Warcraft III, Frozen Throne expantion and to my dismay I find that it will not start! It says “Sorry, Warcraft III could not be opened” Some error… no other info at all!
Downgrade time! I downgraded to 1.21b and the game started up. I then connected to Battle.Net and let it update. Now I can play on battle.net, fully updated without any problems. By the way, here is the patch.
* Note: If you have already connected to battle net and applied the patch from there you can still downgrade using the download above.
