On Tuesday night I left my computer to do the new Windows update overnight, Wednesday morning I went to log in and was getting "side by side" errors for basically every program on the computer. I was able to look at some forums and did a scan through the cmd prompt for something similar to "sfc /scannow" (I don't remember if it was that exactly, but close to) which ran a scan on the computer. After restarting everything is working as normal, except FSX. I have the Steam edition and normally will start up Steam, and then select FSX from there. I tried that and get this error in the screen shot below. I also tried to go into the FSX folder and run FSX.exe but I get the same error message just in a Windows text box. I'm not sure what else to do or why this is now only having an effect of FSX. I have tried to run the sxstrace.exe as it says in the error message, but nothing opens up, or seems to happen. I have tried typing that into the Windows search bar and tried to run it as an administrator through the windows file explorer.
I also saw in a forum it could be an issue with C++, I downloaded the file I was supposed to, but it will not install because it says there is an older version already installed. I'm not sure what to do with that as I don't want to make the computer worse and I'm not really a computer tech.
Any help or ideas are greatly appreciated!
