If that was one click, then its probably sending parameter 536870912 (0x20000000) on the button press, and 131072 (0x00020000) on the release, using the same control (69751). Check in the PMDG documentation. You can duplicate that in your assignment. Cheers, John

1. Yes - just rename your FSUIPC4.ini file as FSUIPC5.ini (located in the Modules directory of your main sim install folder) 2. Yes - just keep a backup of your FSUIPC4.ini (or FSUIPC5.ini) files, and any specific aircraft profile files if you use that feature (located in the Modules/Profiles subdirectory) and restore them to re-use. Cheers, John

Your setting are saved in the FSUIPC5.ini file, located in your Modules folder (under your sim install directory). Make a backup and restore that to get you settings back. If you use profiles in separate files, you would have to backup the profile file for each aircraft (they will be called <aircraft>.ini and located in the 'Profiles' subdirectory under the Modules folder). Cheers, John

zero termination of strings is 0x0 ('\0'), not 0x30 ('0'). Try with that. John

The IVAP Installer is for 'FSX and Prepar3d' and is dated 25/12/2014, so is looking for FSUIPC4/P3Dv3. There are instructions on how to install IVAP with P3Dv4 + FSUIPC5 here: https://flightsimeindhoven.com/prepar3d/install-ivap/ If you have installed correctly and are still having problems, you probably need to talk to the IVAO/Ivap support first. Regards, John

All offsets are defined in the offset status document 'FSUIPC4 Status of IPC Offsets for FSX' which will be in your 'FSUIPC Documents' sub-directory of your FSUIPC installation directory (usually in 'Modules' under your sim installation folder).
