Did you follow the link in LadyCFII's post above to THIS post?

That is where you will find two download links. One link downloads the MS EXCEL VERSION, and the other link downloads the FREE EXCEL VIEWER VERSION. If you have MS Excel on your computer, pick the first one. If not, pick the second one.

If you also need the link to download the free excel viewer, just ask here (or look in the plant tycoon guide section - it is buried in one of the responses there).

Good Luck!
