(Exception from HRESULT: 0x8007007E)" What can I do please?

Answer 1

You may have a dependency on an assembly that only exists for 32-bit or hasn't been properly installed in the GAC. and follow the remarks on the DllImportAttribute Constructor msdn documentation.

Ref:
The specified module could not be found. (Exception from HRESULT: 0x8007007E)
the specified module could not be found 0x8007007E
The specified module could not be found. (Exception from HRESULT: 0x8007007E)
Unable to load DLL 'foo.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Answer 2

Is the DLL in your package? Add it to the project and make the type Content. If it is not deployed with your app, you can't use it.

Answer 3

I had some issues with that too. My solution has been rather simple and not given in any other place:

Copy the next two dlls in the same folder:

libgcc_s_dw2-1.dll

libstdc++-6.dlll

I tried to use "mylib.dll" in a cpp coded aplication and the system asked me to include those files. And suddenly, the app I was developing didn't complain any more about not being able to find "mylib.dll". Don't asky me why.
