Are BluePrint sceneries compatible with Windows 7?
Yes, they are. The sceneries and the scenery installers have been tested in Windows 7 (32-bit and 64-bit) and no issues have been found. (Please note that you still need to obtain 64-bit compatible installers for all our older sceneries released before KMEM unless you purchased them from our web site within the last 90 days.) A bug affecting both FS2004 and FSX in Windows 7 that affects the procedure for adding new areas to the scenery library has been identified. The circumstances and extent of this bug remains unknown. Please see the next answer for details.
