Anyway to Have Two Copies of EQ on Your Computer?

[lonegreywolf20]

I have three HDDs, one is my windows drive, the second my non-gaming program drive and the third my gaming drive. I have a copy of EQ: Titanium installed on my computer already that I use to play on the Irreverent server.

I would like to install another copy of EQ so that I can play on here. However, when I try to do that, it just puts up a modify/repair/uninstall window. I doesn't seem to let me install another copy of EQ: Titanium.

Is there a way to put a second copy of Everquest on my computer?
