    Dear Developer community!

    First of all thank you for your effort with these plugins.

    The latest plugin is working without an issue with my BeamNG if I start with the Launcher, but I started a project myself which is required a BeamNGpy to control the main sw from outside.

    For this the Python coltroller start the game with this command line:
    BeamNG.drive.x64.exe -nosteam -console -tcom-listen-ip 127.0.0.1 -lua extensions.load('tech/techCore');tech_techCore.openServer(64256) -userpath C:\Users\bosch\AppData\Local\BeamNG.drive

    I'm starting the Beam like suggested in the official document:

    beamng = BeamNGpy("localhost", 64256, home="\BeamNG.drive.v0.34\game")
    beamng.open()

    And if I would like to use my SimTools I've got this error message:
    See the end of this message for details on invoking
    just-in-time (JIT) debugging instead of this dialog box.

    ************** Exception Text **************
    System.ComponentModel.Win32Exception (0x80004005): A 32 bit processes cannot access modules of a 64 bit process.

    at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)


    It is the same issue appear if I just doubleclick to BeamNG.drive.x64.exe in Bin folder. But everything is working as expected with the Launcher.

    It would be really any case of help :)

    Thank you!

    Hi @Badrick,
    BeamNG sends its data over UDP. It's like Live for Speed where it actually sends its motion data to 4123 and its dash data to 4124 (How its setup in v3 plugin anyway) It looks like your starting the game up with a different port is all - 64256. Now this should not cause the error you show above (simply missing data as its going somewhere else)

    I'm not sure what is trying to connect to the games 64bit module, as the game simply sends data over udp and the output is caught by the game plugin. There is no direct access of the games modules here.

    Looks like your using SimTools v2, I suggest you give SimTools v3 a shot. As I don't have the source code for the BeamNG v2 plugin, so I can't say for sure how its currently working. But I see no reason you should get these problems with the v3 build of the plugin.

    To be honest, I'm not sure what exactly your doing with python here. But it may be worth seeing if python is running in 32bit or 64bit mode. As it sounds like its directly interacting with the game. If your using the 32bit version, it could cause this error. (A 32 bit processes cannot access modules of a 64 bit process.)
    Please let me know how it goes,
    yobuddy
