Hi all,I have recently been having this fatal error problem on start up of the sim ( Blue loading screen). I decided to do a reinstall, problem still there. I did a complete uninstall and reinstall, deleting every thing to do with FSX, no addons installed, nothing. The sim worked. However, I then installed SP1 and the message came up. I can fly without SP1 thats okay but the PMDG 747 needs SP1 to install. Quad core Q6600 2.43 gb ram9800 gtx750 gb hardrive. Thanks,Zach

Did you uninstall SP2? When doing a reinstall - you need to do this first, then uninstall FSX, then clean the system, reboot, then start the reinstall process. After the base fsx is installed - fly one default flight, quit, then install SP1, followed immediately by SP2.

I did uninstall SP2 first yes. However, I didnt install SP2 after installing SP1, I am currently doing the process again, (uninstalling everything) For a clean install, I will install SP2 after SP1. I read that you should open the sim after SP1 before SP2, to configure it or something.

No - not so: You only need to start the sim after the initial install: then install SP1 followed by SP2. I found that having had SP2 installed and running for a few days/weeks/months - that if I reinstalled FSX, ran it, then installed SP1 and ran the sim - it crashed, but if I installed SP1 and then SP2 straight after it - FSX ran perfectly. Don't ask me why - it just did. This is not just once, but a number of reinstalls.

Ahhh, I wish I would of looked back at this thread, I did everything again, but booted up FSX after SP1, error, then tried SP2, cant install because not English version.... Well it is. I will do reinstall again and install SP2 straight after SP1. Thanks, I will tell you if it works..
