I have updated from Origin50 to Version 7. In Origin50 I was using external DLLs (created by a C++ compiler). In Origin 7 they don't work anymore. What's the easiest way to adapt these DLLs to Origin 7 without having to write newones in Origin C?
Are you refering to a MOCA or MODLL DLL? If so then you may be able to simply recompile your DLL using the libs that came with your version 7. See the ATI/MOCA/ folder in the Origin installation folder.
