Multiple versions of WoW!

[Torgrimmen]

How do I download multiple versions of WoW? Please tell me how, I have 4.2.2 now and I want both, 4.2.2 and 2.4.3

If you're running on Windows all you have to do is rename the last folder where WoW was installed to. Windows simply checks its last installation, so if you rename the folder (even if just temporary) it will not see it, therefore allow you to click the "Install WoW" button and install a new version.
