Help!Just upgraded from Vista -32bit to Windows 7- 64bit with a fresh install of FSX and Accelaration. Just loaded NGX and tried first flight. It loads onto runway and bang FSX crashes to the desktop.Tried with latest hotfix to no avail. I am completeley stumped. All default FSX aircraft are perfect. I really dont know what to do. Any suggestions please!!

Did you reboot and load a flight in FSX between vanilla FSX, acceleration and flying NGX?

Shannon, Is it a new PC with Win7-64 pre loaded?

New Hard drive installed with Windows 7 loaded on. I copied my NGX onto a disc before the new system was loaded. I have installed it from the disc.

The fun begins ....

Shannon, I think you (should) install like the first time you did it!

I did. I am downloading it again from PMDG to see if that(for some reason unbeknown to me) might just do it. Windows crp I say. I only got Windows 7 64 bit to rid myself of the occasional OOMS.She ran well on Vista before with the odd OOM here and there. I really hoped this would have no problems. I loaded a fresh install of FSX ,started it and ran it, then I loaded Acceleration and ran it. I then loaded NGX and ran it,it then crashed FSX .I then loaded the latest hot fixalso from my copied disc as I did not trust the backups which also resulted in a crash to desktop. I will also download the Hotfix again.Further than that I dont know. Perhaps a ticket?

Ok,Check your DLL.xml after next install (as Administrator).Check Windows event viewer and see the "name" of the module that failed last time.

Try downloading the latest C++ 2008

Ok as well as C++ 2010?

01h10 am now,will have to carry on tomorrow as work starts at 6am . This NGX is a real obsession . Will carry on tomorrow evening,thanks for the assistance.

Some words of faith: I gave up with my old Core2Duo 6550 under XP32 and decided to 'half' upgrade: not to expend too much money, I decided to install a quadcore Q9550 so I could use my existing MoBo. Also I jumped from 2GB to 8GB of a C6 DDR2 memory and, obviously, installed Win7 64 on a new 500GB HD. Not too much money invested and what a GREAT surprise. After many and many hours installing Win7 and tons of updates, plus a fresh FSX+Acceleration and REX, I installed NGX. My settings are at least high or very high and the aircraft is flying like a bird. At 2D I'm getting almost 50 fps which is the limit I set. At external view 45+ fps and at VC 23+ fps. No more crashes, no more freezes. I have made three 45 min flight and just finished a 4 hour flight from MPTO to MMMX. The only problem is IVAP crash - both internal and external - but with no consequences to FSX - which is a known issue to devs and it is expected to be solved on SP1. About 'the skeleton' effect it is still there but it lasts less then 1 second to refresh the external view. Just a 'blink'. And it only appears when I change from 2D cockpit to external view after some minutes flying. When I'm using VC and change to external view there is no 'skeleton' effect. Also the problem I usually had - 'black terrain' - is gone. Obviously I was pushing too hard on my old SO install as now it works like charm. Regards. Schmid

I would suggest not installing FSX where you have:C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\fsx.exe I would start again, and install FSX in it's own Dir eg C:\ FSX.Don't rush it. Biggest mistake to make is to rush, I would suggest reading NickN's tunning guide @simforums, and take it from there. Make sure UAC is off.

Thanks will try again in a few hours.
