Well, I tried for an hour and searched this site and couldnt find anything on how to install wow Twice, but its actually really simple.
1: Insert Disk 1 into the D Tray.
2: Click Start on the bottom of your screen and hit the "My Computer" button you see in the window that pops up.
3: When it opens right click the D Tray and hit "Explore"
4: When the new window opens copy all the contents of the folder to a new folder named WoW PVT 1 or WoW 2 w.e u feel fits.
5: Repeat this for the next 5(in some cases 4) disks and when it asks "will you Over write?" Click yes to all
6: When all your disks are done go to your original wow folder and Rename it to something like World of Warcraft2 or WoW2 w.e you feel fits.
7: Then go into the New WoW folder and click the Install button you see, when you get a new dialogue box find your new folder and use that as your directory to install WoW.
8: this could take from a half hour to a day.
The significance in this is that now that when you try and Downgrade your WoW it doesnt go from 2.1 to 2.0 you have a brand new WoW and your old wow
the Install also goes much faster as you dont have to switch disks mid install because all the Data was copied into the folder.
i will be getting screen shots soon to make it easier
