    @Kent-Dorfman said in libwireshark.dll load problem:

    He may have used "/" instead of "".

    This does not matter as long as Qt functions are used... this is what's Qt is made for.

        to add to my mates, this error can also mean, that a dependency of the DLL you want to load is missing. Please check with Dependency Walker.

        Regards

        Qt has to stay free or it will die.

            HI.
            I know, it will seem a stupid question, did you check file exists and path is correct?
            "The specific module could not be found" seems file is not exist or directory is wrong

              @aha_1980 I thought about this issue before, so the dll path i am using is actually where the wireshark is installed, all the dll files are there. If some dlls are missing, wouldn't wireshark fail to start ?

                @lee64456546 According to this https://www.wireshark.org/docs/wsdg_html_chunked/ChIntroAutomated.html Visual Studio 2013 is used.

                  @lee64456546 I don’t know libwireshark.dll, but if it only is a modulo for external tools and Wireshark doesn't use it is possible Wireshark runs well, even though dependency is missed.

                    @CP71 Also, along those lines, I see forward slashes in the directory path. I don't remember if Qt is smart enough to handle UNIX path separators on windoze...I only ever code in NIX so it's not something I ever run into. The OP didn't post where he initializes the name of the dll. He may have used "/" instead of "\".

                    I can confirm Qt works well if you use / in folder name in Windows, but I'm being honest, I hasn’t never loaded a library with Qt.

                        Hi,
                        I have tried your code and have same problem.
                        I think is a dependencies problem.

                          I have found out this link, it is old but maybe is current yet:
