Two errors, No class and Unable to decode

[gizmocodes]

So I'm trying to mod an app, and when decompiling it I get these two errors:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: C:\Users\mcgiz\Desktop\APK\.\jd-intellij\src\main\native\nativelib\win32\x86_64\libjd-intellij.dll
        at java.lang.ClassLoader.loadLibrary(Unknown Source)
        at java.lang.Runtime.load0(Unknown Source)
        at java.lang.System.load(Unknown Source)

        at jd.core.Decompiler.<init>(Decompiler.java:17)
        at jd.core.Main.main(Main.java:16)

So this seems to be missing an IntelliJ library, and after installing IntelliJ it still persists. And the other error:

Here it seems it couldn't decode something, not sure what however. Only argument on the command is -p; problem persists even if removed.
