Error in loading DLL [on hold]

I have a reader for RFID and some UHF passive tags imported from China. They given us demo software written in Delphi that reads the EPC of the tag. However the Dll is of 32 bit and we are not able to load the dll in our windows platform.I would like to get reader byte data and analyze using Linux. Please suggest me a solution for the above and also a better Middleware for developing RFID.
