I just spend 24 hours to make the new PMDG 737 work. It turned out that the "runway.csv" file, which is made when you run the "Makerunways.exe", is causing a CTD when you try to load the PMDG 737. As soon as you turn it off in fsx root there is no problem.It looks like RC4 works without this file ? Will it cause any problems in RC if I delete this file.? Regards

According to the file description:RUNWAYS.XML (Airports and runways for "It's Your Plane"). RC does not use this. It will be created every time you scenery rebuild, however. I am curious, though, why PMDG departs with the NGX from using their own folder under FS to store their data and why the aircraft sees this data. Maybe you want to post on the new PMDG 737 NGX forum here on AVSIM about this.

Thank you for your quick reply Ron. I have posted it on the PMDG forum along with the solution. I just wanted to be sure it was ok to delete it for proper operation of RC4. Regards

i don't understand. runways.csv is an output of makerwys.exe what are you turning off? you don't ever run makerwys.exe by itself. it is run for you, when you click the rebuild rc scenery database. but rc does more, that is why you can't run makerwys.exe by itself. after makerwys.exe is finished, rc then reads the files it creates, and properly formats a new a4.csv, r4.csv, etc in the \data directory of rc i don't know what pmdg has to do with makerwys.exe, with runways.csv, or anything else. jd

That is correct. The runways.csv is made when you rebuild rc scenery database. I understand it is used by IYP. The things is, that pmdg 737ngx does not work with that file active in the fsx root folder. Makerwys.exe is ok. Thanks

I don't like correcting the boss but you do run makerwys.exe in the FS folder directly first if RC is on a networked client to an FS host on a WideFS network before doing the scenery rebuild from within RC. runways.csv and runways.xml have been added to the makerwys output. Here from Pete's documentation; "Runways.csv This is a comma-separated text database of all the runways, sorted, and it is in the particular format used by Radar Contact (all versions up until the change to the following: R4.csv This is the same as the previous CSV file, but includes additional runway data added at the end of each line. This is used in Radar Contact 4 (before RC4.3) for more precise ATC operations. R5.csv This is the same as R4.csv but with runway closure indicators in an extra two fields - CL closed for landing and/or CT closed for take-off. This file is used by RCV4.3 and RC5. " Runways.xml was described in Pete's release notes for it regarding It's Your Plane.

I've just installed the PMDG 737NGX and had no problems. There are three "Runways" files in my main FSX folder: Runways.txtRunways.csvRunways.xml They are all static files (not "active" or "inactive" at all) which are used by one or other programs, or maybe none. They are just listings of data from your scenery created by MakeRunways for use by a number of add-ons, though most don't need them retained permanently in that folder. RC extracts the data it wants and creates its own files in its own folders. I honestly cannot see any way that anything PMDG have done will be influenced by any of these data files in the FSX folder, and that is borne out here. I suspect you have something else going on. Possibly another add-on your have (not RC) which uses that file and which then, consequentially, causes the PMDG code to crash. I'd certainly report this to PMDG if I were you -- if they have enough details they can probably help you determine which other add-on it is interacting with. Otherwise you may need to determine it yourself via a process of elimination. RegardsPete

Thank you all for your help and support on this one. After updating my scenery database within rc4 and then deleting the Runways.csv I can run rc4 without any problems. Pete is probably right that it is a scenery add on that I have and which is read by the runway.exe and put into the runway.csv file, that causes the pmdg to crash. I was lucky to find the cause of the fsx ctd when I selected fly now with the pmdg ngx. I used a program named " Processmon" to find the exact process and time of the crash and I am very happy that I can turn off the Runway.csv file and still enjoy RC4 to the full. Fantastic program for an IFR freak like me. I will also add that I have more than 300 scenery layers and my FSX folder weighs in at 120 Gb total. That is many add ons that also can cause a lot of trouble. Regards

I didn't think it was RC4 which had the problem. you said FSX was crashing when you loaded the PMDG 737NGX.

Pete is probably right that it is a scenery add on that I have and which is read by the runway.exe and put into the runway.csv file, that causes the pmdg to crash.

No, i didn't say that, and in fact that is not really possible. It doesn't matter what scenery is included in the Runways files, it is NOT an "active" file, it is just a collection of data, and it is not used by PMDG at all. What I actually explained was that you may have another add-on which is reading that file and then causing the crash, and that add-on simply stalls earlier if the file isn't there. Since neither RC4 nor any PMDG program reads that data file whilst FS is running, neither are really involved. Using ProcMon you should have been able to identify what program component was actually accessing the file. I don't know of any which use it directly during an FSX session.. RegardsPete

I will try and run Procmon again when I start up the 737ngx and look for app and programs that has errors.Thanks for clarifying this Pete. Rgds

Guys, I used the 737NG on Friday with RC 4.3 and all worked without a problem.This appears to be a problem on Michaels system. Norman

It is the 737NGX he is having the problem with.

It's still a problem with his system - I use RC4.3 and have no problems with the 737NGX, or any other plane, with runways.csv, runways.txt, or runways.xml... DJ
