Upgraded to Windows 10 yesterday. Have been reinstalling FSX today (that's another story), just done the basic install and Accelerator plus Steve's DX10 fixer. I was running in DX10 previously (on Windows 8.1) because I use two monitors and both monitors only worked correctly in that mode. In DX9 the images stretched across both monitors - distorted both images. DX10 and Steve's fixer worked perfectly.
All was working fine in DX10 except for the problems the fixer fixed - now the fixer is installed I get a fatal error when I click 'fly now'.
Has anyone got DX10 running OK in Windows 10? Thanks
