Why not? Please show me a log file for this. This usually happens if you have the DetectToConnectDelayAuto ini parameter set too high, and are not waiting long enough for it to connect., If assignments to presets or lvars/hvars/calc. code stop working mid flight, this is usually a sign that the FSUIPC WASM module has crashed, You can prevent this by setting a WASM ini parameter to stop repeated scanning for new lvars - see MSFS have not made it easy for 3rd party developers. Everyone has different add-ons, different PC specs, different controllers, etc. FSUIPC should work pretty much out-of-the-box for most users. However, some initial configuration maybe needed If you have many add-ons and it takes MSFS more than a minute or two to arrive to the main menu state. But even then, FSUIPC will auto-tune itself - but you need to exit MSFS and restart once MSFS has arrived at the main menu AND FSUIPC has connected. Once toy have done the initial set-up/tuning, you shouldn't need to do this again. Auti-tuning will still monitor the connection, and if multiple connection attempts are detected, it will flag auto-tuning to be ran the next time FSUIPC is auto-started by MSFS. For this to work correctly, you need to make sure that you are still in the MSFS main menu when FSUIPC7 connects.

Yes - there weren'r that many updates between these versions, and nothing that could cause a CTD. The log file you attached ends after 80 seconds - so did P3D crash on start-up? Of so, that is usually a sign of a corrupt weather file. Try setting "NoWeatherAtAll=Yes" in the [General] section of the FSUIPC6.INI file to disable weather - if that fixes it, then you have a corrupt weather file which needs to be removed (see that FAQ entry I referenced). If thats not it, check the Windows Event viewer to see where the crash occurred, and maybe check the P3D forums for similar CTD reports.

Ok, although i don't know why you previously said 'The Workgroups are the same'! Once that is corrected, try again. If you still have issues, try setting the ServerName (or ServerIPAddr) and the Protocol - see the WideFS User guide, and also the WideFS Technical guide for troubleshooting network issues. Ok, but you need to sort this out - I can;t help with this... John

Please see the section Auto-tuning of initial start-up ini parameters in the Advanced User guide, and/or the following FAQ entry: No idea, Everyone suffers from CTDs at some point. It is up to you to determine the cause... John

Your log file shows that you didn't load an aircraft and get to the ready-to-fly state, and toy exited after 205 seconds... Apart from the first entry, the numbers are not in the correct position. Maybe the case also matters...try: John

Would be helpful if you attached your FSUIPC4.ini file, but it looks like its coming from an assignment (index 32, to button 8 on device 3) to a lua file, the one with index number 7.

Please respond to that questions - and all my questions. I cannot help if you do not respond. But with which axis? I can see entries for Ruder, Ailerons, Elevator and throttle. Lets try this again... First, choose one axis and let me know which. Then perform the same test, i.e. with logging for Axis Controls activated, just load your aircraft, and move the assigned axis through its full range and back again. Then exit FSUIPC/FSX, and save/copy/show me the FSUIPC4.log and FSUIPC4.ini files. Next, perform the second test. Do exactly the same as before, but change the reverse setting on the axis you are testing. Then exit anf show me/attach those two files again. i.e. two distinct tests, each with two files, trying one axis (and let ma know which!). This is FAR easier of you just look at the values logged in real-time...for example, this is what I see moving my throttle through its full range: i.e. the Param value foes from 0 to 16384 and back again. If I now go into calibration and reverse the axis: it now goes from 16384 to 0 and then back again. So the parameter values have been reversed. (Note the actual range depends on which axis control, but whatever the range, it should be reversed when the Rev checkbox is selected). John

Are you using the correct Active Sky dll (as_connect.dll) for the version you are using? Please check that first. Otherwise, weather CTDs are normally caused by a corrupt *.wx fille, so please check this - see If you still get crashes, please show me your FSUIPC6.log fo;e, as well as any crash reports for this in the Windows Event Viewer. Again, check that you are using the latest version of AS6 and have the correct AS dll installed (if using). I do not provide old and unsupported versions - I only move foreword. I doubt very much this has anything to do with the change from 6.2.0 to 6.2.1, but I have attached the 6.2.0 dll below for you to confirm. John FSUIPC6.dll

No, I cannot. What has this to do with FSUIPC? If your issue comes from an upgrade of the Sim-Avionics 777 flight model, why don't you raise this issue with them rather than here? I know nothing about the Sim-Avionics 777. If you have an issue with FSUIPC I can help, but I do not support 3rd party products/add-ons from other developers... If you have assignments in FSUIPC which aren't working, regardless of which aircraft you are using, then I need to see (attach not paste) your FSUIPC6.ini file (which contains your assignments), and also your FSUIPC6.log file, with appropriate logging activated (i.e. Buttons & Switches and Events (non-axis controls)) that shows what is happening. It could be something simple, such as an aircraft name not currently caught by a profile, or possibly a device GUID change that has made your current assignments obsolete. But I can't really comment without seeing your files. John

203 is the elevatiuon of the aircraft, and the ground elevation was 194. This is normal. However, what changed was that the ground elevation received at timestamp 952687 changes the ground elevation to 0, hence the issue - as I previously showed: So the ground elevation of the aircraft IS changing, as received via simconnect. So something somewhere is changing this... I can change FSUIPC to ignore the difference between ground and aircraft altitude, so it doesn't change the state or the OnGrnd flag. I will provide you with a new version to test this when I have time....

The OnGnd flag is used as received, except when the AI aircraft state is sleeping or waiting for engine start (states 1 and 0). When an aircraft is in one of these states, FSUIPC will look at the difference between the ground altitude and the aircraft altitude, and if this is < 100 it will set/change the OnGnd flag to 1 (internally, regardless of the value received), and if >=100 it will set the OnGnd flag to 0 and change the state (internally) to show the aircraft as Enroute. This is why it is shown as airborne. I am not sure why FSUIPC does this - maybe the OnGnd flag (plus other data fields which are also changed) cannot (or could not) be trusted for such aircraft - I am not sure. I can remove this feature, or maybe add an ini parameter that can enable/disable this functionality. But the real issue is why is the Ground altitude changing to 0 for these aircraft when they are sleeping?

Ok, thanks - I was going to ask if you use any traffic add-ons. I have seen no issues when using standard MSFS AI traffic. I am not familiar with FS Traffic though... There is certainly an issue somewhere....but lot 10 'Shamrock' (Id 3894) (and others) maybe in the STATE_ENROUTE_AS_FILED state, so are Enroute. If you look at the log entries, e.g. See the number in brackets after the state string - this is the state number, where 1 is STATE_SLEEP and 12 is STATE_ENROUTE_AS_FILED. So it looks like there is certainly something wrong somewhere ...for that aircraft, the state seems to change here: For some reason, the ground altitude of the AI aircraft is changing from 194 to 0, which seems to be the problem. When an AI aircraft' altitude is more than 100 above the ground altitude, then FSUIPC will automatically change the state (internally) to Enroute if it is currently in STATE_SLEEP or STATE_WAIT_FOR_ENGINE_START. So this issue seems to be due to the ground height being received (or misinterpreted). Of course, this may also be an FSUIPC issue - I will check your log further and look into this more over the weekend, when time permits, and/or next week. John

But doesn't it also have a component installed in the MSFS community folder, or even update some official files? And if it is only a separate application, it uses other APIs as well as SimConnect. For example, there was a known bug in the NavData API (used by GSX) that could cause the sim to crash, although I believe it is fixed now (haven't followed this though). There are also many reports of MSFS CTDs when using GSX, although this doesn't necessarily mean that GSX is at fault. But its certainly worth trying a few flights without GSX to see if the CTDs continue or not. Cheers, John

Yes, WideFS is a separate program/license, and is composed of two parts - WideServer and WideClient. The registration is for WideServer, which is built into FSUIPC since FSUIPC4 - before that it was a separate executable. This is why you need to register it with the FSUIPC installer. Note that you can also now run FSUIPC7 on a client machine, which is another solution for running clients/controllers in a client PC, and no additional license for WideFS is needed, However, this is not the same as running WideClient on the client PC, so may not be suitable for all use cases. See the appendix in the Advanced User guide if interested in running FSUIPC7 in a client PC. Note that you cannot run both WideClient and FSUIPC on the same machine, although both can be installed if you want to try and switch between the two. John

Yes Ok, that's good. Do you see the same issue in the FSUIPC TCAS tables then (or in TrafficLook)?

No - there are still no functions to export the wxr radar image as far as I am aware. so this is still not possible. John

WideClient isn't connecting to WideServer/FSUIPC. You need to sort this out before anything else. Please see the WideFS documentation on connection issues (check your Workgroup name!), as well as other forum posts. Do you see '...wth WideServer waiting for clients' in the titlebar of FSX? If so, WideServer is running but WideClient is not connecting - you need to correct this before anything else. All firewalls - client, server and routers? Your FSUIPC4.log file shows that this was attached while FSUIPC was still running - please ALWAYS exit FSX/FSUIPC before attaching files. And also please attach your WideServer.log file the next time.

Ok, that sound sensible. But I don't think there is anything I can do about this issue anyway. It has been around since 2010 at least, and seems to be an issue with RC4 and so needs to be fixed in RC4. If there was a possible fic in this for FSUPC, I would have thought that Pete would have done this a long time ago. Pete was also an RC4 user, and I have no experience with RC4 and so cannot really help much with this issue. I am certainly not going to go through a 400Mb log file to try and understand what RC4 is doing to look into this...! John

What changed to give this message? Did you re-install FSUIPC or P3D, or anything else? Try uninstalling FSUIPC, either by double-clicking the uninstallFSUIPC6.exe file or via the windows app management panel, and then re-install FSUIPC into the same folder and try again. If you get any issues, show me your InstallFSUIPC6.log file as well as your add-on.xml file - the location of which can be found in your installation log (it is usually under Documents\Prepar3D v5 Add-ons\FSUIPC6). John

If MSFS crashes, you need to look at the Asobo forums. FSUIPC7 is a separate application and it cannot cause MSFS to crash, and the WASM is sandboxed - if that crashes, it should not affect MSFS. Your WASM log shows no issues - except that it didn't exit cleanly (as MSFS had crashed), and your FSUIPC7.log shows no issues. I think your issue may be with GSX - I have heard a lot of reports of CTDs with GSC, e,g, see https://forums.flightsimulator.com/t/gsx-ctd/537743/7/, Have you tried without GSX? Other than that, as I can't see how this can be anything to do with FSUIPC. Not really. This just means that you may not be able to distinguish an lvar by name, using FSUIPCs lvar facilities, as it will be truncated to 55 characters.

The log file is again useless as it is a continuation log, has excessive logging and is not logging what is needed (Axis Controls). I do not even know which axis you are talking about - your ini file shows that you only have reversing set on your Throttle. Is this the axis you are trying to reverse? Please do the following: - activate logging for Axis Controls. - move the axis you are having issues with through its full range. - go into FSUIPC's calibration and change the reverse setting - move the axis you are having issues with through its full range again, in the same direction as before. Then show me the log file. Do the in/Out values change/reverse when you change Rev setting? i.e. if you move your axis in one direction without the Rev option checked and the In/Out values are positive, then if you check Rev and move the axis in the same direction, the values should now be negative - is that not the case? Which aircraft are you using for this?You should update all your profiles to use substrings to catch all variants, e.g. change: to Also , if this is with the FSLabs A320, can you also try a different aircraft to see if it is specific to the FS Labs, Some aircraft to not play well with FSUIPC calibration - if this is the case, you need to remove the calibration in FSUIPC and scale the axis to reverse, as I mentioned in my earlier post. John

The log file you attached is a continuation log - please only provide full log files, i.e. do not start a new log. You also have logging for IPC Reads and Writes activated for some reason, and no logging for Events or Buttons & Switches. And I cannot see when this change of view is occurring - only you. So try again, but only with the suggested logging activated, and keep the logging console window open. Then look to see what is logged when the unwanted view switch occurs. This may then tell you where this is coming from, if its from an FSUIPC assignment. Do you have anything assigned to witch to the external view? If you attach your FSUIPC4.ini file I can check. John

You can try using FSUIPC's logging - set logging for Events and Button & Keys and take a look at the FSUIPC7.log file when this switch occurs and see if you can see the event that does this - if it comes from FSUIPC you should also see the assignment as well.

If the axis goes through calibration (do the In/Out numbers change?) then I can't see how reversing the axis doesn't work - please show me/attach your FSUIPC7.ini and DSUIPC7.log files. If the axis doesn't go through FSUIPC calibration, you need to use an axis scaling factor of *-1 - see the Advance User guide (page 42).

Does your FSUIPC7 key still validate? If so, you are entering it incorrectly or you are using a different name and/or address for your WideFS key. If that is the case, check the appropriate box and enter those details. Otherwise, let me know your WideFS7 order number and I will check your key here.
