Hi Ander thank you for response.
I installed from NuGet fo-dicom 1.1.0.
say that the structure of my application is as follows (project and bin folder):
Application.exe (main)
Dicom.dll
Dicom.Native.dll
Dicom.Native64.dll
Then this error appears when I try a transferSyntax.
exactly here : var dicomfileSp = new DicomFile(datasetCp).ChangeTransferSyntax(DicomTransferSyntax.Parse("1.2.840.10008.1.2"));
This error only appears in "windows server" for others windows (7, 8, 8,1, 10) there is no problem with the same operation.
Regards.
