I recently had to send my computer in for some repairs and they messed up some files in my Fmcwp and elsewhere...My Question is: I want to reinstall my FS9 in it's entirety and keep FS10 as is. Do I go into the add/remove & do it that way PLUS go into program files for FS9 and make sure everything is deleted there and is that sufficient to clear everything out for a fresh install of FS9 and will any of this affect FS10?? I've never had to do this before so I'm not familiar with some of the in's & out's of it!!Hope somebody can give me a 'heads-up' on what to do so I don't mess anything else up.Anybody care to take a stab?Regards,jack

Yes, do the uninstall, delete the program files file, plus the application data ( where the cfg. file is located.) Then do some kind of registry clean. There are free programs to do that.Bob

Bob,Thanks for the 'heads-up'...Should I also delete the other files under:Application Data Microsoft Fs9 Aircraft ?? Facilities ?? Scenery Cache ?? FS9 (Config. file) Wxstationlist ??Also, do you know the name of a 'good' FREE registry cleaner?Regards & thanks again for your inputs.jack

I have used CCleaner and a cleaner by Glary. Sometimes both. Bob
