problem with orarrp!

I have a problem with orarrp when i start orarrp.exe by certified applet!
The error message is: Check a suitable application is installed to handle files(error code 31).

The source that start orarrp.exe is:

     try  {
			String comando = "c:\\orarrp";
			Runtime rt = Runtime.getRuntime();
   	    		Process p = rt.exec(comando);
   	    		
   	 	}
		catch (Exception e) {
   	 		System.out.println("error exec:"+e);
		}
		return;
