Hello-this is my first post on the forum and trying to get someone who might help.I'm running a 64 bit sytem on Windows 7 with FSX. I've the 737NGX as an add on, I keep getting a fatal error.

I've moved it from the program 86 folder and just onto the c drive because I read on here that might help.I'm not much good as a flight sim person and am trying to use this as a training aid as I've flown the aircraft for years-but not in the last year-so I'm trying to use this as an aid before I fly again--but I cannot evenfly it on my own computer and am hacked off with my lack of computer knowledge.I guess I should really go to PDMG for support but since I think it's the FSX I've come here hoping somebody can point me in the right direction please?

Welcome to AVSIM. Sorry your first post has to be in the CTD forum! I'm confused by your comment that you moved "it" from the Program (x86) folder to the C drive. What is "it"? I'm assuming you reinstalled FSX to your C drive instead of the default folder which is okay. However, if you first uninstalled FSX from the default location, then installed to the C drive, you could have some corrupted registry entries and they might still think FSX or PMDG737 is still installed in your default location thus causing the crash. Try running the free registry repair program from Flight1 - http://www.flight1.com/view.asp?page=library. I'm assuming you have FSX Deluxe and Acceleration installed or FSX Gold or FSX Deluxe, SP1 and SP2. Does FSX only crash when you load the PMDG 737NGX?

 

If that doesn't work, uninstall the PMDG737 then reinstall. Make sure you have all updates to the product installed (SP1c was the last one). Before you install it, run FSX and make sure it's running properly. Turn off any anti-virus program running and disable UAC (click on the Start button, type UAC in the search box then look up and click on How to Charge User Access Controls), then install the aircraft.

 

Hope this helps.

 

Best regards,

Jim

Jim, thanks for the input-I appreciate it!.I've ran the registry repair program but didn't seem to change.You're assumptions are correct-I I've the program onto the c: drive.I think FSX is running ok because the normal 737-800 looks to me.In the 737 NGX the instruments seem compressed and distorted and it eventually crashes anyway.I'm running i core 5 with a ge-force 405 graphics card-I thought that would have been enough?-I will remove 737-NGX and try again-only thing is I'll need another code from PDMG to reinstall which is a pain.I think that program is more trouble than its worth to be honest.

That sounds like your system is struggling to get sufficient resources to run the PMDG 737. The PMDG is not a resource hog but it does take more power to run it than just the default aircraft. You only need serial number for your PMDG product once. It came with your purchase. Just uninstall and then reinstall with the serial number that came with the product.

 

I would also look at reducing your FSX settings back to the default and see if that fixes the problem. If it does, slowly start moving your sliders up.

 

Also, make sure your virtual memory (page file) is set to system managed size. This has fixed several problems in this forum. Click on the Start button and in the search box type virtual memory, then look up and click on How to Change Virtual Memory Settings.

 

Best regards,
