If you are absolutely sure that your OS, Java and the DLL are all 32-bit, then you may be missing the Windows implementation of libpcap library. Try below steps:

1) Uninstall any previous versions of jpcap

2) Install winPcap and then, run the jpcap installer

3) C:\WINDOWS\system32\Jpcap.dll (check it exists)

4) C:\WINDOWS\Sun\Java\lib\ext\jpcap.jar

5) try running your java Program again. Ensure that you have -Djava.library.path=C:\WINDOWS\system32\Jpcap.dll in your Java launch command.
