java - JavaFTD2xx OS not supported error for 8 Channel Relay -

i got 8 channel sain smart usb relay here: http://www.amazon.com/sainsmart-eight-channel-relay-automation/dp/b0093y89de/ref=sr_1_sc_1?ie=utf8&qid=1443224362&sr=8-1-spell&keywords=8+channel+relay+sain+smart

i trying connect device on windows 64 bit computer java. have downloaded of source code javaftd2xx project supposed utilize ftd2xx driver located on github.

the ftd2xx driver downloaded located here http://www.ftdichip.com/drivers/d2xx.htm

i downloaded 64 bit windows version , ran executable.

i opened javaftd2xx project in netbeans , created main class. here code main class.

 list<ftdevice> ftdevices;      //ftdevices= ftdevice.getdevices(true);      ftdevices = ftdevice.getdevices();      (ftdevice ftdevice : ftdevices) {          system.out.println("ftdevice:" + ftdevice);         system.out.println("ftdevice.devtype:" + ftdevice.getdevtype());         system.out.println("ftdevice.devid:" + ftdevice.getdevid());         system.out.println("ftdevice.devlocationid:" + ftdevice.getdevlocationid());          ftdevice.open();         ftdevice.setbaudrate(9600);         ftdevice.setdatacharacteristics(wordlength.bits_8, stopbits.stop_bits_1, parity.parity_none);         ftdevice.settimeouts(1000, 1000);          ftdevice.setbitmode((byte)0xff, bitmodes.bitmode_sync_bitbang);          // set true (energised) or false (not energised) each relay (1 4)         boolean relaystates[] = { true, true, true, true };          int value = 0;         (int i=0; < relaystates.length; i++) {            if (relaystates[i]) value += (1 << i);         }         ftdevice.write(value);          ftdevice.close();      }  

the error getting operating system not supported. further code, issue input stream null code below.

if (platform.iswindows()) {                 in = loader.class.getresourceasstream(                         "/natives/i386/ftd2xx.dll");             } 

i have checked, , platform.iswindows() return true. have checked see if file exists in folder (i copied , pasted folder project) , see file. however, loader.class.getresourseasstream sets in null. can please either me working or provide other solution in other language. don't mind doing in language, preferably java.

thanks!
