... I know this answer, but don't remember it... I do remember though that MSTS does cause issues on Win10 on my machine downstairs, which is an old Core2 quad. Do you have all of the updates available for MSTS, including the after-market ones? I'll see if I can look on the computer downstairs and get you some links. Seems to me this has to do with the DirectX files, but I am not certain. You could try to re-install the
DirectX v9.0c run time, which if you have an SH4 install disk, it is on it, else you would have to use the MS online version. As for Monopoly, I am not familiar with it, but it might also be an older game and has some system requirements like MSTS and/or SH4. Unfortunately, there are a LOT of DirectX and Visual C++ library files, each with slightly different files inside, and it might be that one of the games you have overwrites the files of the previous. My computer downstairs has a dual-boot Win7/Win10 set-up, and I have it currently set to only be able to run MSTS in Win7, due to issues with it in Win10. I have a separate SH4 install copy for each of Win7 and Win10. All of those have folder names designating where I can run them, such as SH4Win7 and SH4Win10. I look and see what I have for MSTS downstairs, and see if I can find you some links...
