P3Dv4.5 & FSPUIC 5.155

Recommended Posts

Good evening all,

I have just done a fresh install of P3Dv4.5 and I added FSUIPC as I need it to make FSXWX tool works. However, I am experiencing a freeze and CTD without an error message upon completion of the loading of the scenario (so aircraft on the runway, works for about 5 sec then freeze and CTD).

I have the following installed:

- PMDG Aircraft / Captain Sim Aircraft

- REX Sky Force

- ORBX Global

- I have downloaded a weather injection tool call FSXWX (http://www.plane-pics.de/fsxwx/home.htm)


I have attached my log:

I have quickly established a link between the installation of FSUIPC and the CTD. I therfore remove the loading lines of the module in the DLL.XML and it doesn't crash...


I am a free user of FSUIPC as you can tell by the log therefore I understand I may not be entitled to the level of support of a customer. But I normally manage to fix most of my issue on FSX/P3D but I must say, I am stuck on this one. Let me know if I need to provide other data.


Kindest regards,

first thing is to eliminate to which program actually is causing the problem. As FSUIPC is the interface that is used by other program to read/write data it is most likely not the problem. Disabling other add-ons and adding them step by step.

The problem might be a corrupt weather file, best is to delete those from saved flight that will be loaded.

To avoid any forced read of weather data please add this to the [General] section in FSUIPC5.ini file



FSUIPC5 for Advanced Users.pdf

General weather options
NoWeatherAtAll provides a diagnostic facility to make FSUIPC avoid all weather reading and writing activities. This
is invoked by adding “NoWeatherAtAll=Yes” to the [General] section of the FSUIPC5.INI file.

Good evening Thomas,

Thanks for the quick reply, greatly appreciated. You gave some good thoughts about a weather issue related and I put back the default wxmapping.bin into my P3Dv4 Weather folder. I also added the line to my FSUIPC.ini and it worked like a charm. Could you please advise if the line you asked me to add to my FSUIPC.ini will have an effect in using FSXWX tool ?

Kindest regards,

the added line forces FSUIPC to not invoking FS Weather, as the registered version has some facilities to do so. But mainly it doesn't force P3D to read the weather file from saved flights. When those are corrupt P3D will crash as soon it gets to it.

External WX programs are not effected as they normally inject the weather direct into P3D or using FSUIPC Offsets if not that advanced.
