WIndows 10, can not load dll's #10

Closed elucidator closed 8 years ago

elucidator commented 9 years ago

Nicholas,

I'm starting out with the myo on java. Got WIndows 10 and JDK 8 running, but i cant load the DLL's.

I specified the -Djava.library.path=c:\tmp and placed the 64 bit DLL's there. You know of any limitations on WIndows 10?

Below is the stack trace I have, Two thing i find strange, first the name of the JNI library, it ends with 64 (and yes did a copy with that name as well) ANd it tells me its not a valid Win32 application?

Suggestions.

(And no i do not have C compiler running :-) )

I have the same problem.

NicholasAStuart commented 9 years ago

I haven't tested on Windows 10, so I'm not sure if it will work or not. I'll try testing this in the next few days once I get a machine capable of testing.

What version are you using? Testing on My Windows 10, I don't have any issues. You shouldn't have to specify -Djava.library.path=c:\tmp, as the JAR should install it already for you.

I have the same problem our JNI was warking fine with previosu versions of windows and suddently started to be unable to load dll on various custommers running windows 10 most of customers working fine but some of them are unable to load DLL I have no idea what is happening...
