I previously purchased WITP AE via Download and it installed on my computer with no problems. I am now trying to install that copy onto a second computer. I can copy/paste all the WITP AE folders/files onto this second computer, but I was unable to find any app/exe file that would enable me to install it.

I do not own a CD of WITP AE so I am unable to load/install game using that method.

Question = Is this correct: the only method I can use to install WITP AE on my second computer is to again purchase the game on the Matrix Site and download it onto my second computer?
