Reply: Placing the file in the system32 directory allows it to be called by the main program. If the call is not successful, there are two possibilities:

1. An old file with the same name exists in the main program installation directory, and in this case, the program will prioritize calling the old file.

2. The Java runtime environment is not properly configured. You need to add the search path: C:\Windows\System32 to the Java runtime environment.

Reply: There is no 64-bit nbiobspjni.dll file currently. Did you encounter a message that nbiobspjni.dll could not be loaded during development? You can try to do this:

1. Put nbiobspjni.dll in the C:\Windows\system32\ directory

2. Then quote this in the code:

Public class Main {
Static {
System.load("NBioBSPJNI.dll");
}
Public static void main(String arg) {
System.out.println("Hello world!");
}
}
