java.lang.UnsatisfiedLinkError: Unable to load library ----> JNA on Windows

[azadigb]

1. Version of JNA and related jars ----> 4.2.2
2. Version and vendor of the java virtual machine ----> Java 1.7.0_55 - 64bit
3. Operating system ----> Windows 7
4. System architecture (CPU type, bitness of the JVM)----> Intel Core I3- 2120
5. Complete description of the problem
   I am trying to load the .dll file I have built from my C/C++ project on Windows 7. I have created a small piece of code in Java to load the library with JNA, but it gives me the following error.

Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'C:\Users\Local\Temp\libMCS.dll': Native library (win32-x86-64/C:\Users\Local\Temp\libMCS.dll) not found in resource path ([file:/C:/Users/Agolbamaki/workspace/test/bin/, file:/C:/Users/workspace/test/jna-4.2.2.jar])

I guess it cannot find the .dll file eventhough it is copied in the current directory (almost in all the possible directories). I also tried to copy the .dll in a TEMP directory and load it by an absolute path.
It automatically adds a prefix to the library path (win32-x86-64/C:\PATH\Temp\libMCS.dll).

Thank you for your help

Please check that you have the Visual C++ Runtime 2010 64bit installed.

Are you setting the property "jna.library.path" to the location of your
DLL? Are all dependencies of that DLL in the same directory?
