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 -

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 "\".

@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.

Hi,
What version of Wireshark did you download ?
-
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.

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

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. -
