After some time of OK, but not outstanding operation, it would get as far as "FLY NOW!" then go to a black screen, often with sound, but unable to gey any visuals, not even the top of screen menu with ALT.
Tried simplest default flight, but still no go.
Ran Acceleration repair, says OK.
Ran FSX repair, says computing space req.......copying new files,,,,,,,(no green progress bar)....Data error (Cyclic redundancy check)....Error 1603- Fatal error during installation...Consult Msi.chm Done that, ran unregister followed by register server........Tried again, no difference....Shut down, leave off for hours, tried again, no difference.
If the installation can change to the point of failure, I'm losing confidence in the value of doing another complete reinstall.
Dump a billion dollars of software and get XPlane?
