Hi Team,

I built the latest version of Orthanc and downloaded latest version of OpenSlide library.
I want to convert svs to DICOM WSI.
I get the load library error, see below,

C:\Orthanc\OrthancWSI-1.1\Applications\Build\Debug>OrthancWSIDicomizer.exe --openslide=C:\Orthanc\openslide-win64-20221217\bin\libopenslide-0.dll C:\Orthanc\TestFiles\CMU-1-JP2K-33005.svs

E0115 10:11:20.481806 Dicomizer.cpp:1122] Terminating on exception: Error while using a shared library (plugin)

Kindly help me.

Thanks,

Hi,

Error 126 means the DLL can not be loaded, usually because:

  • it’s not at the right place
  • it’s not the same 32/64 bits architecture as the process calling it
  • the user does not have access to it
    If this does not help, check what happens with Process Monitor.

BTW, do you know that these tools are included in the Windows installers ?

HTH,

Alain
