unresolved external symbol with FTD3XX.dll

Question

Using VS2005 on an MFC project, I can't make any function call to FTD3XX.dll by using the lib FTDI provided (USB to Serial)

Imported the FTD3XX.h file and added the FTD3XX.lib to Additional dependencies under Linker > Input.

None of the calls will work, for example:
FT_STATUS status;
DWORD dwNumDevs;
status = FT_CreateDeviceInfoList(&dwNumDevs);

It keeps failing on unresolved external symbol meaning I did not import the DLL properly.

What am I missing here ?
Thank you

Answer 1

Resolved by using another .lib file.

It is possible that the DLL I tries to use was compiled on an older VS.
