Maybe your .dwg file is too new, the dll only supports formats up to 2018,
see: CAD DLL[^]

ok but it is throwing error while creating object of the form and for loading the image we have code in frmDMSViewer
cadPictBox.ImageLocation = FileName;
cadPictBox.Load();

also can you please suggest link that i can use with this 6.3 existing version as when i tried with version 11 it doesnt have cadpicbox.Load or imagelocation method

Can't be of much help I'm afraid, I never used that dll and only found this information on Google. Try posting your question on the forum of the manufacturer.
