My friend is trying to download my client onto his computer, but when he tries to play the game, he gets a message saying "component 'richtx32.ocx' or one of its dependencies not correctly registered: a file is missing or invalid". We copied and pasted the richtx32 to his system32 folder, opened up cmd, and tried to manually register it, and it gets an error message saying it cannot be found. His OS is windows XP. Any suggestions?
