NaMcO Posted January 27, 2022 Report Share Posted January 27, 2022 Hello, I know we are in an MSFS era or even P3D V5 (i use them both too), but i am a nostalgic person and somehow i missed FSX and all my huge library of addons and decided to reinstall everything and enjoy it for a while. I faced a ton of issues with LVLD.dll and FSUIPC4 (crashes on FSX startup after a few seconds, can reproduce easily), finally managed to solve them by using an older FSUIPC4 DLL (4.9.4.7) up until the third or fourth launch where it decided it couldn't see SimConnect anymore and i had to reinstall FSUIPC again (4.9.7.7), after removing and reinstalling all 4 SimConnects. I don't know if all are required, maybe some older addons connect to a specific version, so... Thing is, the problem once again returned. I can fix it by either disabling LVLD.dll or FSUIPC4.dll in the DLL.XML file, both cannot live together as it is. So, my question is simple: Is there a known compatibility issue between these two DLLs? Should they be loaded in a specific order so that they can work together with no issues? Is there a specific FSUIPC version that will work with LevelD latest version 1.50? This is my DLL.XML file: <?xml version="1.0" encoding="Windows-1252"?> <SimBase.Document Type="Launch" version="1,0"> <Descr>Launch</Descr> <Filename>dll.xml</Filename> <Disabled>False</Disabled> <Launch.ManualLoad>False</Launch.ManualLoad> <Launch.Addon> <Name>ObjectFlow.dll</Name> <Disabled>False</Disabled> <ManualLoad>False</ManualLoad> <Path>C:\Program Files (x86)\Steam\steamapps\common\FSX\ORBX\FTX_AU\FTXAA_ORBXLIBS\Scenery\ObjectFlow.dll</Path> </Launch.Addon> <Launch.Addon> <Name>PMDG Events</Name> <Disabled>False</Disabled> <Path>PMDG\DLLs\PMDGEvents.dll</Path> </Launch.Addon> <Launch.Addon> <Name>PMDG Options</Name> <Disabled>False</Disabled> <Path>PMDG\DLLs\PMDGOptions.dll</Path> </Launch.Addon> <Launch.Addon> <Name>PMDG Sounds</Name> <Disabled>False</Disabled> <Path>PMDG\DLLs\PMDGSounds.dll</Path> </Launch.Addon> <Launch.Addon> <Name>SODE Animation Module</Name> <Disabled>False</Disabled> <ManualLoad>False</ManualLoad> <Path>C:\Program Files (x86)\12bPilot\SODE\SimObjectAnimationModule.dll</Path> </Launch.Addon> <Launch.Addon> <Name>Level-D Simulations</Name> <Disabled>False</Disabled> <Path>Modules\LVLD.dll</Path> </Launch.Addon> <Launch.Addon> <Name>IvAp</Name> <Disabled>False</Disabled> <Path>C:\Program Files (x86)\IVAO\IvAp v2\ivap_fsx_bootstrap.dll</Path> <Commandline></Commandline> </Launch.Addon> <Launch.Addon> <Name>FSUIPC 4</Name> <Disabled>False</Disabled> <Path>Modules\FSUIPC4.dll</Path> </Launch.Addon> </SimBase.Document> Any help towards solving this (apparent) compatibility issue would be highly appreciated. Reinstalling FSUIPC again will not solve it. Link to comment Share on other sites More sharing options...

No idea - this is the first time I have heard of the LVLD.dll. Is this something that is used by the Level-D Simulations 767? Id so, ir seems strange that is is being loaded from the DLL.xml, i.e. for every flight, even if not using the 767. Or is this something else? 9 minutes ago, NaMcO said: Should they be loaded in a specific order so that they can work together with no issues? I don't know.... Sometimes the order does matter, so just try switching the order, to see if that helps. 10 minutes ago, NaMcO said: Is there a specific FSUIPC version that will work with LevelD latest version 1.50? No. I don't understand why an older version of FSUIPC4 would work but the latest not. Omly the latest version of FSUIPC4 is available and supported. 12 minutes ago, NaMcO said: Any help towards solving this (apparent) compatibility issue would be highly appreciated. I really do not know what to advise here. I you tried support from Level-D Simulations? If you attach your FSUIPC4.log file for when FSUIPC4 crashes on start-up I can take a look. This may reveal something. John Link to comment Share on other sites More sharing options...

Or is this something else? Yes, it is used by the 767 and apparently it controls some features in the aircraft, if it is not loaded, the aircraft will not initialize properly. There is an option in the 767 menus to "only load the DLL with LevelD 767", so it will only activate if the aircraft is selected (apparently), but changing this does nothing. 18 minutes ago, John Dowson said: I don't know.... Sometimes the order does matter, so just try switching the order, to see if that helps. Yeah i did that. I thought it would be better to let FSUIPC set all the hooks before all other addons, tried it last as well, before and after LVLD.dll to no avail. Only works by disabling either LVLD or FSUIPC. 18 minutes ago, John Dowson said: No. I don't understand why an older version of FSUIPC4 would work but the latest not. Omly the latest version of FSUIPC4 is available and supported. Me neither, maybe some changes that were introduced in the latest versions could cause this? I am clueless really, just trying to figure this out. 18 minutes ago, John Dowson said: I really do not know what to advise here. I you tried support from Level-D Simulations? If you attach your FSUIPC4.log file for when FSUIPC4 crashes on start-up I can take a look. This may reveal something. No, but i will post in their forum. If all else fails, i'll just give up on LevelD 767 (let's face it, it's REALLY old and i'm lucky it even flies today in Windows 11). The logs don't show much. A normal log with no crashes is just a clean startup/exit and the one with the crashes is interrupted.

It will consistently crash after a few (20-30) seconds, no matter what i'm doing (selecting an airport, an aircraft, loading the simulator scenery, simply idling on the startup screen, etc): Link to comment Share on other sites More sharing options...
John Dowson Posted January 27, 2022 Report Share Posted January 27, 2022 Sorry, no idea why its crashing. You are also using an unregistered version, so FSUIPC isn't doing that much, just requesting data from the FS and using that to populate the FSUIPC offsets. 2 hours ago, NaMcO said: No, but i will post in their forum. If all else fails, i'll just give up on LevelD 767 (let's face it, it's REALLY old and i'm lucky it even flies today in Windows 11). Ok, lets see what they say...

John Yeah i only use it to feed my ACARS, i do have a registered copy but i no longer use WideFS and that was the reason why i bought it a long time ago. Anyway thanks a lot for the prompt responses, i'll check what they say in the forums or try to find a solution somewhere, i understand this is a shot in the dark for a (very) unsupported platform, so i don't expect much really 😝 Link to comment Share on other sites More sharing options...
