    User Information:

    Platform:   Windows  ;   
    Language(s) :     C++  ;


    I have created a plugin that runs in my system as it supposed to (using Visual Studio 2013).
    It creates a folder MyPlugin along with the corresponding menu item.
    Everything works fine.

    Sometimes though, when i transfer the plugin folder to other PCs, it is not loaded in Cinema4D.
    Even when i try to run Cinema4D using visual studio (via cinema4dSDK) i get the messages:

    'CINEMA 4D.exe' (Win32) : Loaded '<path>/my_plugin.cdl64'. Cannot find or open the PDB file.
    'CINEMA 4D.exe' (Win32) : Unloaded '<path>/my_plugin.cdl64'

    Why does it unload the plugin?

    Thank you.

    you need to recompile it, I guess you are doing it in debug mode, in release mode you won't encounter this problem.

    my first bet would be the version of Cinema 4D (actually the API_VERSION). If the plugin id build on a higher version than the version trying to load the plugin, it will fail.
    Usually you can expect your plugins to be upward compatible. For example, I still have plugins running in R17, that have been built against R13. The other way around won't work.
    So, this would be the first thing to check.

    Hello !

    The plugin is built using the R16 Api.
    It also runs in R15 and R17 but it doesnt in R16.

    Please check also the minor version. For example there was a problem within R16, which made it necessary to bump the API_VERSION during R16.

    I have the same issue.

    I compiled on 16.59 and it runs.
    It also runs on 16.050 (Build RB131856).
    I will check with the customer which version he runs.

    For what versions will it fail?

    Thank you very much for your answer.
    Updating Cinema4D version solves the problem.
