I've got both but would like to uninstall FSX without impacting FS9--what's the best way to do it? Do I need to repair the FS9 registry after uninstalling FSX? As a side note, I run FSX in DX10 and have GEX, UTX, ASA, REX. I run nhancer for both FSX and FS9. I don't really use FSX that much anymore--mainly for limited VFR...so I'd like to free up some HD space.ThanksRich PerryIntel i7 Extreme Edition 965 (oc'd 3.8Ghz)Nvidia GTX 285 (2GB)OCZ 6GB DDR3 1800MhzRaptor 10000rpm HDSB Xi ExtremeWindows Vista Pro 64bit

I uninstalled FSX last night after reading several related posts here and other simfori. Long story short is was successful. Here's the order:1) Uninstall all FSX related addons--from control panel--remove2) Reboot3) Uninstall FSX acceleration...which is the only FSX icon thing that shows in control panel remove menu4) Reboot5) Delete FSX folder from wherever you've got it parked...mine was on C:/6) Run registry repair (this is a payware program but there are many others out there)--it yielded over 2500 errors--took 45mins to repair7) Reboot8) Run a thorough defrag (I use O/O defrag)9) RebootGood to go.RP

I uninstalled FSX a couple of times without hurting FS9 with tons of addons, complex planes and sceneries.The best and easiest cure for fixing FS9 registry is to run AFCAD, navigate it manually to FS2004 directory, close AFCAD and run it again. By doing that, you will automatically restore FS9 registry.

or ... if you have an issue ... use flight1's free FS reg. repair tool -http://www.flight1.com/view.asp?page=libraryuse: FSX/FS9 Registry Repair Tool (36KB)--

This is one "fix" I have never heard before - just how does one "navigate Afcad manually to FS2004 directory (folder)" ??More precise details please.Removing FSX will almost always screw up the FS2004 registry entry and I use the free utility from Flight1 to correct it. Simple and effective.

Despite what others are saying I'm sure this is quite helpful to some.
