You know what, Kelti -- I tried to install CFS2 on a Win7Pro machine and I didn't see any option... other than where it said the sim was going to be installed. No option to create your own path, (I use C:\FS Games\Flight Simulator 9) for FS2004, Nothing about the program not installing properly and the option to use a different set of options (i.e. WinXP), or any other means to use to install the program correctly. Sorry mate. Rami said that the X86 folder was fine since CFS2 is a 32bit application so I'm going to have a go and see how it all turns out.

I don't know either.
I work with Win8 at the office, but I have a WinXP Pro pc at home, dedicated to CFS2, meaning without any Web connection and all useless services switched off, devoting the greatest amount of OS resources to the sim.
I never tried installing CFS2 in a 64-bit environment before, but I was told by serious technicians there's an option one can choose when installing an old 32-bit program. An option to run it, or installing it, with the 64-bit emulating an older OS like WinXP. It was explained to me as if, at the beginning of the installation, one could choose an option like
"install as XP" or something like that.
I always did a custom install of CFS2, I am the master of my pc and not its subordinate, so I want things to go where I want them to be. Custom install during the autorun CFS2 setup allows to choose a different folder than the default one. I'd imagine that option would also allow, under 64-bit Windows, to choose the OS emulation, who knows, perhaps via a right-click context menu. I'd have to try it out first, before stating anything else.
I don't know if simply installing in the x86 folder is already an XP emulation, but Rami is right about it: that's the folder where 32-bit applications must go from 64-bit Vista onwards. So far, I never had any troubles creating my own folders in the
"Program Files (x86)" folder at work and direct installations to place 32-bit program files there. There is still a huge number of downloadable freeware 32-bit applications working fine under Win8, I have installed quite a few of them.
Sooner or later, old pcs like mine will pretend to be retired from active duty and a 64-bit environment is the only option for a new machine today. All the issues and problems still being discussed here about running CFS2 in Vista, Win7 and now 8, don't encourage me at all. CFS2 in a window instead of full-screen, huge display problems with widescreen monitors.....
dreadful
!
Creating the 64-bit equivalent of our beloved CFS2 is definitely not in MS' top list, which I see all bent instead in catching up and beating Apple with tablets, I-phones and so on. All gizmo's that I personally judge as impractical toys, albeit extremely beautiful, designed only to add an expensive item to John Doe's everyday budget and not to pave the way to meet the Volcans and found the United Planet Federation as they promise!
Solid proof of MS' today market strategy is Win8, a touchscreen-capable OS, whose interface looks like the real HOT thing, an Apple tablet, but will never be used as such in an everyday work environment!
I immediately downloaded Classic Shell and been working since last October as I always did since Windows for DOS 3.0, 3.1, Win95, Win98 and XP!
Call me Jurassic or anything you want, just don't call me late for dinner! 
Cheers!
