Not because I think MSFT 2020 is the cat's pajamas, but because I'm getting a file not verified error from FSX:SE after I just load FSX:SE. I removed and reinstalled FSX:SE, no joy. My Windows installation is up to date. I've filed a problem report with Steam, and if they punt, I'm uninstalling FSX:SE, Steam, and all of the third party software that I've been using with FSX:SE. And, I'm expecting them to punt. I have the educational version of Prepar3D V.4, so I'll install it, instead, and all of the 3rd party software I have that is compatible with P3D. I'm sure there'll be a learning curve with P3D; Heck, I was still learning new features of FSX after years of using it.
