Play Framework: unable to load native JNotify library

Question

You are having problems running Play Project on my computer with Windows 10 (works fine on Win 7)

When I start the activator, I get the following:

Error loading library, java.library.path=C:\Program Files\Java\jdk1.8.0_111\bin;C:\WINDOWS\Sun\Java\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\cygwin64\usr\local\bin;C:\cygwin64\bin;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Intel\iCLS Client;C:\Program Files\Intel\iCLS Client;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Intel\WiFi\bin;C:\Program Files\Common Files\Intel\WirelessCommon;C:\Program Files\Java\jdk1.8.0_111\bin;C:\Program Files\PostgreSQL\9.6\bin;C:\Program Files\Git\cmd;C:\dev\utils\activator-1.3.5-minimal;C:\Users\shuda\AppData\Local\Microsoft\WindowsApps;C:\Program Files\Heroku\bin;.;C:\dev\projects\energywatch-portal-bk\target\native_libraries\64bits

Cannot load the JNotify native library (no jnotify_64bit in java.library.path)
Play will check file changes for each request, so expect degraded reloading performace.

--- (Running the application from SBT, auto-reloading is enabled) ---

[info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000

(Server started, use Ctrl+D to stop and go back to the console...)

[success] Compiled in 1s

I have tried many things without success. I tried moving from:

addSbtPlugin ("com.typesafe.play"% "sbt-plugin"% "2.2.2")

to

addSbtPlugin ("com.typesafe.play"% "sbt-plugin"% "2.3.2")

and I get another error:

java.lang.NoClassDefFoundError: play/Project$

       ...

So, here is my environment setup now (changing sbt-plugin causes 2nd release)

scalaVersion: = "2.10.3" → from build.sbt

addSbtPlugin ("com.typesafe.play"% "sbt-plugin"% "2.2.2") → from plugins.sbt

sbt.version = 0.13.1 → from build.properties

Again, I'm on Win 10 (64 bit)
