Well it's simple, when I try to install the Chinese WoW it shows up an error message, wich includes come patch numbers like 5.0.0 and 5.0.4. Then it auto-closes the installation.
I wonder if this eror shows up becuase of I got another World of Warcraft Installation already at patch 5.0.4 (In other language).
So the question is: Can I have those 2 WoW's at the same time? If it's possible, how?
