I created a console application and added abcpdf version 22.214.171.124 DLL as a reference:
I copied executable and abcpdf.dll to a server to test. But I got an error:
Unable to load DLL 'ABCpdf9-64.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
My local computer and windows server are 64-bit.
