No. I bought yesterday hoping to see something new to keep improving FS9. The installer hangs with "Prerequisite check for system component Microsoft .NET Framework 4.5 (x86 and x64) failed with the following error message: "Installation of the Microsoft .NET Framework 4.5 is not supported on this operating system. Contact your application vendor."
The day I quit using XP is the same day I waste a ton of money side-grading to FSX and a thousand dollars to make it look like my current FS9 setup. I made a comment on the REX site that they should just come right out and state NOT FOR XP USERS.
