Error with topaz.SigUsb java.lang.UnsatisfiedLinkError: C:\Program Files\Java\jdk1.8.0_201\jre\bin\SigUsb.dll: Can't find dependent libraries

Question

I am developing a Java application that uses SigUsb.dll for interfacing with a digital signature device. However, I am encountering a java.lang.UnsatisfiedLinkError stating that dependent libraries cannot be found, The exact error message is:

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Program Files\Java\jdk1.8.0_201\jre\bin\SigUsb.dll: Can't find dependent libraries

I have confirmed that SigUsb.dll is a 64-bit DLL and my Java version is also 64-bit. I tried adding the DLL to C:\Windows\System32 and setting up the java.library.path correctly, but the error persists.

Here's what I have tried:

• Ensuring that SigUsb.dll and all its dependencies are 64-bit.
• Setting the environment variable PATH to include the directory where the DLL resides.
• Running the application with administrative privileges.

Any insights into why Java might still be unable to load the DLL or suggestions for additional troubleshooting steps would be appreciated.
