FSX with Windows 10

[jwenting]

It all works fine for me, apart from some addon installers (especially those from Flight1) failing to run at all (which is no problem with Windows 10 or FSX but with those installers not being written to work in the security system that's been in place since at least Windows 8, and often Windows 7, if you look at F1s website they bluntly tell you to not upgrade to even Vista and especially not a 64 bit operating system and that they won't support anything newer...).

Most likely you need to upgrade your video drivers.
