According to the link provided in the comments, JD-Core-java is a thin-wrapper for the Java Decompiler to support an IntelliJ IDE plugin. The Java Decompiler itself supports:
- Linux 32/64-bit
- Windows 32/64-bit
- Mac OSX 32/64-bit on x86 hardware
However, the JD-Core-java wrapper currently only supports Linux 64-bit.
You have two options:
- Contact the author and ask for a Windows version
- Pull the sources from bitbucket and port the native code to Windows to build a Windows DLL (and send it back to the author to be included in future versions)
