According to the stack trace (NativeHookServices.java:120) the exception happens here: https://github.com/asterics/AsTeRICS/blob/master/ARE/services/JNativeHook/src/main/java/eu/asterics/mw/jnativehook/NativeHookServices.java#L120

tempDLLs can only be null if 

File[] tempDLLs = tempDir.listFiles(new FilenameFilter()

returns null, which is the case if the given file is not a directory or an I/O error occured (see https://docs.oracle.com/javase/7/docs/api/java/io/File.html#listFiles(java.io.FilenameFilter)).

--> Can other applications access your What is the value of your java.io.tempdir property? Is still space left on your drive?

On my computer there is no problem starting ARE 3.0 (or starting ARE from current master), although I also have installed Windows 10 Update "Funktionsupdate Version 1709".

@stefanstocki Have you checked your tempdir and the space left? Do you still have the problem??

ghost commented 6 years ago

just tested again - now it starts without any problems... @deinhofer you had the same problem in 2016 -> https://github.com/kwhat/jnativehook/issues/101 :)
