You may need it again and it's a lot easier than a Repair or Re-Install. Once you have your FSX up and running properly again, back it up, all of it. You can make a copy of your existing FSX folder/subfolders before the repair and paste those individual files back in afterwards.If you have SP1, SP2, or Acceleration installed, they must be uninstalled before a repair attempt, and reinstalled, after the repair, or it won't work. With a Repair, any default file, including those default aircraft.cfgs with added liveries, that have been modified, tweaked, or otherwise changed, will be returned to default status. 5 min - Uploaded by Pablo GallasProblema de memoria insuficiente en Windows 8.1 y Windows 10 - Duration: 7: 42.This applies to FSX-MS like the label you chose to start your thread.
