%1 is not a valid Win32 application

Question

Hello,
I'm trying to compile and run a tutorial using PKCS11 for tokens. Here's the code I'm using
import iaik.pkcs.pkcs11.Module;
import iaik.pkcs.pkcs11.Slot;
import iaik.pkcs.pkcs11.Token;
import iaik.pkcs.pkcs11.TokenException;
import iaik.pkcs.pkcs11.TokenInfo;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;

         pkcs11Module.initialize(null);
      catch (IOException ex)
         Logger.getLogger(SmartCardTutorial.class.getName()).log(Level.SEVERE,

                                                                 ex);
      catch (TokenException ex)
         Logger.getLogger(SmartCardTutorial.class.getName()).log(Level.SEVERE,

                                                                 ex);
   public Slot[] getTokenSlots()
      throws TokenException
      return pkcs11Module.getSlotList(Module.SlotRequirement.TOKEN_PRESENT);
   public void printTokenInfos()
      throws TokenException
      Slot[] slots = getTokenSlots();
      if (slots.length == 0)
      { // No tokens connected
         System.out.println("Sorry, Couldn't find any token");
      else
         // Let's get the first slot
         Slot selectedSlot = slots[0];
         // Let's get the connected token
         Token token = selectedSlot.getToken();
         // Get the token infos
         TokenInfo tokenInfo = token.getTokenInfo();
         System.out.println("Token : " + tokenInfo.getLabel());
         System.out.println("Vendor : " + tokenInfo.getManufacturerID());
         System.out.println("Serial Number : " + tokenInfo.getSerialNumber());
    * @param args
   public static void main(String[] args)
      SmartCardTutorial sct = new SmartCardTutorial(DLL);
      try
         sct.printTokenInfos();
      catch (TokenException e)
         // TODO Auto-generated catch block
         e.printStackTrace();
}and here's the error I get:

Has anyone encountered this before?

Hi,
You should check the DLL you have. As far as I can tell, this error is coming from the Win32 LoadLibrary call in the iaik native code that is loading the P11 library. I have tried the following code on my system and it works fine.
import iaik.pkcs.pkcs11.Module;
* @author sfarmer
public class SCardToken {
    private final static String DLL_PATH = "./acpkcs211.dll";
    private Module p11;
     * @throws Exception
    public SCardToken() throws Exception {
        p11 = Module.getInstance(DLL_PATH);
        p11.initialize(null);
        System.out.println(p11.getInfo());
    public static void main(String[] args) throws Exception {
        new SCardToken();
}Output:
Cryptoki Version: 2.11
ManufacturerID: ActivIdentity                  
Library Description: ActivIdentity Cryptoki Lib SDKThis is where you are getting your IOException from:
   * Load the PKCS #11 DLL
  hModule = LoadLibrary(libraryNameStr);
  if (hModule == NULL) {
    FormatMessage(
        FORMAT_MESSAGE_ALLOCATE_BUFFER |
        FORMAT_MESSAGE_FROM_SYSTEM |
        FORMAT_MESSAGE_IGNORE_INSERTS,
        NULL,
        GetLastError(),
        0, /* Default language */
        (LPTSTR) &lpMsgBuf,
        0,
        NULL
    exceptionMessage = (char *) malloc(sizeof(char) * (strlen((LPTSTR) lpMsgBuf) + strlen(libraryNameStr) + 1));
    strcpy(exceptionMessage, (LPTSTR) lpMsgBuf);
    strcat(exceptionMessage, libraryNameStr);
    throwIOException(env, (LPTSTR) exceptionMessage);
    /* Free the buffer. */
    free(exceptionMessage);
    LocalFree(lpMsgBuf);
    return;
  }Cheers,
