Hi John, I am trying to use my cpflight COM 1 & 2 radios on vatsim (vpilot) but I am only getting the 25 khz spacing. I tried setting x0B47 and x0B48 offsets to 1 but still my cpflight COM radios have 25 khz spacing. I am running cpflight with Project Magenta software, but I am having difficulty getting a response from PM so I am trying this route. Maybe cpflight does not read fsuipc offsets and it needs to be a change in the PM/cpflight driver. If this is a dead end (if PM don't help) I presume I could buy, say, an Opencockpits COM 1 & 2 and simply set the above offsets in their sioc script, as OC obviously does use fsuipc. I only need the COM radios to be able to change frequencies on vpilot, there is no other need for integration with PM logics. Regards Charles

John, no worries, I can work around the input event issue. Take your time to find the CTD. Karl

I can see the issue - the parameter is converted to an integer rather than a floating point value, so 0.5 is converted to 0. I will correct this. I could provide you with a beta version, but I have discovered a very strange issue that I need to fix before I can provide any more updates. For some (unknown) reason, all builds since sometime mid-April have an issue with showing the 'Find Preset' panel, and pressing the 'Find Preset...' button causes FSUIPC7 to CTD. Its a very puzzling issue - no code change and even re-building existing released versions, where there was no issue, now suffer from this problem. It is very puzzling - and worrying.... John

Please take your time, John.

Hmm, strange....I will take a look and get back to you.... Unfortunately I had a catastrophic crash on a windows (Insider) update last week and have had to re-install Windows, as well as MSFS, P3D, etc. As well as my development environment. No recent backup unfortunately either (the last one I had was from 2023!). So it may take a few days... John

If I trigger an input event like in the screenshot, assigned to a button it's ok and the mixture lever of the Carenado Dakota moves to mid position (every position from 0.0 to 1.0 works) and the linput event log shows: 253672 InputEvent received: ENGINE_MIXTURE_LEFT=8192.000000 (param=';FLOAT64') If I do it from a Lua script, nothing happens. ipc.execInputEvent("ENGINE_MIXTURE_LEFT", 0.5) The log shows: 257828 InputEvent received: ENGINE_MIXTURE_LEFT=0.000000 (param=';FLOAT64') There's probably something I do not understand. Karl

FSUIPC7 7.5.3 and likely other external apps using SimConnect and crashing FS24 SU3 1.5.10.0 are solved in FS24 SU3 1.5.12.0 It was even mentioned in the release notes! For now I a happy simmer again.

Thanks a LOT John, you are the BEST !!! Claudio

This is support for FSUIPC, not Mobiflight - try MobiFlight support (on Discord). John

You can use a lua script to operate the mouse, but I would not recommend this. You would need to move the mouse cursor to the correct position before sending the click, and the position could change depending on the view. Note that the versions of FSUIPC for P3D and FSX had a mouse macro facility, for sending mouse clicks to specific 'mouse rectangles' defined in the aircraft. However, this facility is not available in FSUPC7 as MSFS does not support this. There are 3 different ways that you can achieve this: 1. Define your own preset to activate all of them (in the myevents.txt file) and use that. Just define the preset to send the calc code of each individual preset. I showed how to do this for the PMDG 777-300ER in another post: Not sure if they work in the 777-200. You can try them - or correct to use the 777-200 light presets if different. 2. Define a macro to send each light preset. Macros can be used to send multiple commands on a single button or key press - see the Advanced User guide for details un using macros. 3. Overload your assignments so that you have multiple preset assignments on the same button. To do this, assign the first preset. Then open the FSUIPC7.ini file and comment out the assignment (add a semi-colon after the '=' sign) and reload the assignments. Then assign the next preset. Then comment that one out. Repeat until you have all the assignments you require, then uncomment out the assignments previously commented out. When doing this, make sure that you edit the FSUIPC7.ini file with the button assignments panel open, and click 'Reload all buttons' when you have saved the changes, to reload the file. John

Take a look at the offset mapping document for the PMDG 737 (Offset Mapping for PMDG 737NGX and 737NGXu.pdf) - note that you need to enable data broadcasts in the PMDG to have these offset populated. There is this offset (1-byte each, for each engine): or maybe this one: The current position of this switch is also held in offset 0x64FC: John

I support everything you have said Dutch 100%. I'm just a little frustrated and disappointed. I won't go into it, but throughout SU2, I was in direct contact with support and they continued to blame things on my end. I knew it wasn't my end as I wasn't the only one with the same issue. Then they released an update that fixed everything and now with SU3, support have stopped giving feedback, advice on the beta. I'm at the stage now, where I don't have any hope for 24. They committed to a release date, when they were obviously well behind and they have been chasing their tail ever since.

'm using a Boeing 737 FlitePal engine start switch, which is made with a solenoid. I've configured the GRD, OFF, CONT, and FLT switch positions using PMDG Event IDs. However, for the solenoid's ARM function, I need an output (annunciator). I tested this with X-Plane 11 using the Zibo mod and utilized the "Start Valve Open" DataRef, which was easy to identify with DataRef Editor. It worked correctly, disarming the solenoid at the right time, specifically when the "Start Valve Open" annunciator extinguished on the EICAS. My current challenge is finding this same "Start Valve Open" information within PMDG (for their 737) or FSUIPC. I'm looking for an equivalent offset or variable that I can use as an output to control the solenoid's arming.

Hi this is my first post and am building a 737 cockpit. I am using Mobiflight and have been having an issue with this exact topic. I see the offsets listed for the A/P A/T AND FMC. I guess my problem is I really don't understand how they are supposed to be programmed in Mobiflight. I apologize in advance if this is really dumb but could someone take a few minutes and let me know the steps to making the TEST 1 and TEST 2 switch illuminate the three indicators on my panel and how that sim delivers the alerts to my panel when they fire in the sim. The TEST 1 and TEST 2 switch when I activate it on my panel does light the proper indicators in the sim. And when I run a MOBIflight test all the LED's do illuminate properly. Thank you again!

I don't mind being a Beta or Alpha tester I know that this means yes you will run into bugs and crashes. But I actually want to support the Asobo and Microsoft teams in making the best simulator, for me it's actually part of the hobby. The last two beta (alpha) versions where very troublesome. With version 1.5.9.0 I ran into crashes when getting in the cockpit all FS20 aircraft also the official ones that come with the sim and some of the 3rd party FS24 aircraft. But there was no mention in the release notes of 1.5.9.0 that can explain that you can get crashes getting into aircraft. With version 1.5.10.0 we ran into FSUIPC and many other external apps crashing the simulator. Again there was no mention in the release notes of 1.5.10.0 that could explain changes that are causing these crashes. I get it we are beta testing the sim but as a former developer I'm starting to wander what is going on behand the seen. It seems we are not getting the full version of the release notes I think there are way more changes and bugfixes happening. This can eventually result in code that gets more and more difficult to maintain and les reliable. It the old days we would just call this spaghetti code but let pray I am totally wrong. So it's a good thing the teams are not at the Flight Sim Expo 2025 and I agree this says a lot.

Hi, i am using the PMDG 777 200 and there are some points in the screen where you can click with the mouse for example to switch on all the landing lights all togheter. I did not find any preset to activate all of them at once but just the left, center, right but i have just a button available. Can i assign to that button a "mouse left click" (0x20000000) ? How to do it if possible ? Thanks in advance Claudio Damiani

I don't mind being a Beta tester. This is more Alpha. I get bugs and CTD's, but something should be done to fix them quickly, at least to a point where the product works. You can't ask people to spend almost $300 and then ask them to beta test bugs that cause them not to be able to play the game. What I'd expect is a small team, to pre test an update, to a least make sure it doesn't crash the sim and then release it to players on the beta to report back and then if something major is found, a fix is done over night or at least the next day. They told us they couldn't go to the expo because they were hard at it, yet no update over the weekend to fix their unplayable game. Truth is, they didn't want to face the backlash.

That's why it's a Beta version.....We are the testers......🫣

Disregard, Windows Antivirus blocked the install. All is working!

I am attempting to install version 7.5.3 for MSFS2020, but the installation process fails and displays the following error: "Extract: error writing to file installing and Registering FSUIPC7.pdf." All component toggles are selected, and I cannot attach a screenshot since it exceeds 20kb. Despite the installation appearing to complete, certain files seem to be missing. Additionally, I am unable to install a previous version as it is not available on the download page.

You dont have to buy again - all upgrades are free. You just need to download and install the latest version. John

I had bought an earlier version and presumed it was working, as on Win 10 I had no problems. Now I have to buy the latest version to work on Win11?

External apps seem to be the biggest issue. Xbox users on the forum seem to have little to no issues. Meanwhile us PC users are going nuts over it. I just hope when it comes out, that FSUICP and all the other apps go back to working. I find it hard, that an organisation the size of MS/Asobo, didn't test this before releasing it.

Great testing and I totally agree that it's very likely a SimConnect is the issue. A lot if external apps seem to result in CTD. Let's see and wait what SU3 1.5.11.0 will bring us.
