I Have just purchased a new off the shelf gaming PC and can't get FSX to run in Windows 10 (Home Edition). My old PC was self built 10 years ago with an i7 chip (stock speed of 3.2 gigs, overclocked to up to 4 gigs); dual graphics cards and 12 gigs of ram. I was running Windows 7 Pro and did mostly airline flying with nearly all of the WOAI packages installed and edited so that all liveries properly displayed.
My new system is an off-the-shelf Asus gaming desk top: i7 9700K processor, 16 gigs ram, Nvidia GeForce RTX 2080 Graphics card with 8 gigs of memory, 500 gig SSD for C drive, 1T HDD for D drive.
FSX will install, but after you set up a flight and hit "fly now", the screen goes black and just sits there playing the FSX intro music for as long as you are willing to listen. I have the FSX Gold edition, and initially installed all three discs. After discs 1 and 2 installed, I registered using the product key, then continued with the installation of the Acceleration Expansion package - disc 3. The registration for the expansion failed and I got an error message each time I tried to load the software.
Doing some research I found where people said the Acceleration package would not work in Windows 10, so I removed the software and reinstalled using just the Deluxe Edition (discs 1 and 2 only). I have removed and reinstalled the software several times, have changed the compatibility modes, and run as administrator. I no longer get any error messages, just the above result of listing to FSX music while watching a black screen.
I installed FS9 and Combat FS2 by just copying the software from my old backup drive to my new D drive, and both worked first time. I tried this with FSX but I get the same result as when I install from the disc.
Back in 2015 when Microsoft was first coming out with Windows 10, I tried the switch on my old computer. I was able then to get FSX to work in compatibility mode, but initially unable to get FS9 or CFS2 to work, because both programs required a disc to be installed to run, and Windows 10 did not recognize that. I went back to Windows 7, but later found the fix where you don't need the disc. So that's where I am. If anyone has any suggestions, I would really like to get FSX up and running.
