Installing HotDate

[Blistex]

I've just made this copy of Hot Date on my friend's computer (I don't have any burner myself). He's got a Samsung CD-R/RW Sw-212B burning at 12X max. We used Clonecd. I can launch the install program, I get through the serial key number, but then it asks me to specify the correct cdrom drive letter. I browsed the forum and didn't find anything relating to installing the Sims expansion. I just can't get to install the game! Can anyone help me on that one?

P.S.: Sorry, I'm a newbie and english is not my native language.
