Just got back from a lengthly sojourn and would like to get an answer as to how to download the infamous NGX using my current Win7 home edition software. I have the FSX version of the MD-11 on my I7 930 dell computer and I believe the MD-11 is loaded into a x86 platform which is......I think the system 32 directory. I would like to download the 737NGX into a 64bit directory and would like to know some of the details as to how you accomplish this as all my FSX files...I think again are in a 32bit directory...Can anyone tell me how I can download the NGX into a 64bit format or do I have to erase everything I have on FSX and start over?? My system specs are: i7-930, 9 gig of ram, 1.5 ter H.D., and a 5770 Radeon graphics card with 1gig................When I initially downloaded the MD-11, it went into an x32 bit folder. Will the NGX also go into a 'X32' bit folder also and negate the benefits of having the NGX run on a 64bit platform?? What should I do at this stage? Dump FSX and the MD-11 and start over with the whole process or is there an option to place the NGX into the 64 bit platform????? jen noulet

In order to have the NGX in 64bit directory you need to have FSX there first as the NGX is going to be inside FSX root files. If you need to know how to do it, when installing FSX you will see that the installer is going to ask you if you want to place FSX in C:/Program Files(x89), you just erase the (x89) or change it completly to C:/FSX and which is what is most recommended and thats it.

All, Time out!! A few things here: 1. FSX is a 32 bit program. It doesn't change anything where it is installed, in regards to this. Also, there is no such thing as a 64 bit format. 2. Planes get installed into your FSX folder. So wherever that is located, that is where this plane will get installed also. 3. Jen, if your FSX is running fine, then just install as you did the MD-11.

Well, I think what you are saying is to just download the NGX and it will find my FSX folder and install it there. My MD-11 runs great where it is located, however, I'm still a bit confused as to why so many on this forum talk about the big differences in operating under 64bit versus 32bit etc..??? I still just a little bit unsure of where it's going to end up with the download and what type of performance I'll have after the download is completed not knowing where this software is going to nest-in at...Thanks for your replies. jen noulet

Hi, You are confusing the conversations of using a 64 bit operating system vs. a 32 bit operating system, not the physical location of your FSX installation. The software is going to end up in your FSX folder!

A 32bit system only uses up to 4gb of ram memory it don't matter how much more you have installed in your machine while a 64bit system uses all the ram you can install in your system. That is why many people see a difference in performance when they upgrade to a 64bit system.

Technically a 32bit Operating System such as Windows 7can only use 3.80 gigs or memory somewhere in that ballpark. This makes FSX prone to OOM's out of memory errors, and that's why PMDG and most other people who want to run FSX worry free get the 64 bit version of their OS.

Jen, Here's the explanation: There are two types of base level CPU machine code for Windows PCs. 32-bit code is called "x86", named after the series of Intel processors that executed it from the old days -286, 386, 486, 586 & 686 (branded "Pentium") etc. 64-bit code is called "x64." FSX is a 32-bit x86 application and all PMDG products including the NGX are 32-bit x86 applications. There are actually very few games/sims coded in x64 as of yet. As a user, you cannot make a 32-bit app into a 64-bit one - it has to be coded for it from the start. As for where things get installed: 32-bit versions of Windows have a "Program Files" folder where most programs default to installing. 64-bit versions of Windows however have both a "Program Files" and a "Program Files (x86)" folder. 32-bit programs by default get redirected to install in Program Files (x86) while actual native 64-bit programs go to Program Files. This is just an organizational scheme by Microsoft. A 64-bit program is still a 64-bit program regardless of where it's installed and it's the same for 32-bit programs. The NGX and any other FSX addon aircraft is going to install to the FSX folder - it doesn't care where FSX is installed, it'll always go there. In fact, on Vista and Win7 we recommend installing FSX to its own folder outside or the two normal Microsoft ones - for example C:\FSX or D:\Games\FSX. The reason is that those operating systems have "protections" that exist for anything installed into Program Files or Program Files (x86). FSX is a old application developed before both OSes were released and it tends to not play well with the protections - you can see a lot of strange errors like addons that can't save their options or route files, liveries not showing up etc.

G'day Ryan and Jim. Just in process of installing FSX and NGX on a new system. This is my first experience with Win7 X64 coming from XP (X32). On the new system I have two HDD(s), WD 500GB for the OS and the second a 1TB for FSX. As I understand it I must create folder FSX on the 1TB HDD and then custom install FSX to that folder. Now how about the addon progies such as Active Sky Evolution, ORBX and Flight Sim Commander. Should I create a second folder on the 1TB HDD (which has FSX) and name it "Program Files" and the install the addon(s) in there or (I think) most would need to be installed inside the FSX Main Directory so in that case I just need to show path to where FSX resides i.e. D:\FSX during the install for example of Active Sky Evolution.

Install location of stand-alone addons like REX, ASE etc aren't nearly as crucial - I think it's still a good idea to put them outside of Program Files/Program Files (x86), but it's not critical. If you want, just make a folder on your FS drive called "FS Apps" or something and install them all to that folder. ORBX stuff installs to the FSX folder in the ORBX subfolder so you don't need to worry about that.

Thanks Ryan, Just one other question, FSX will be a clean fresh copy with SP1 and 2.Normally I would install FSUIPC next but in view of what you say in the Introduction tutorial for the NGX, FSUIPC can cause problems if you calibrate flight controls. Would you agree that the NGX should be installed prior to any addon like FSUIPC and ORBX also prior to tweaking the FSX.cfg?. Steps being:1. Install fresh copy of FSX plus SP1 and 2. Adjust display settings2. Defrag the system.3. Adjust graphics with Nvidia Inspector.4. Install PMDG 737NGX.5 Tweak the FSX.cfg using ******* Altuve progy6. Install FSUIPC but avoid any control calibration.7. Install ORBX (FTX scenery)8. Install Active Sky Evolution.

Say you turned of UAC before you even began to install a single shread of FSX or anything related to it, would you still need to modify its original placement? Or is the problem happening when users leave their UAC turned on?

I've got UAC turned off and FSX installed in the default location (C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X) and I've never encountered problems running FSX or any addons, including PMDG J41 and MD11. Andy Lawton
