I had a couple troubles installing FMS here.
First, when it asked if I wanted to install DirectX 6, and I said yes (didn't know then I already had version 7), I ended up losing some or all of the installed FMS files at completion. Worked though when I said no.
Then, when it asks where in the Start menu I want it installed (so many app setups never even ask), it never goes where I specified (Flight\FMS). The Program shortcut is always in the Start\Programs menu.
Will this be fixed in the next beta?
