(Looking at the Capture1.PNG you attached)
Erm.... You supposed to install that Java (JRE), not just put it in the Stencyl folder....
That's not how it works.
I got a feeling your PC is using a 32bit Java (JRE), that is currently already installed in your laptop.
You need the 64bit version.
Download the latest "Windows x64 Offline" version (2nd from the bottom) :
http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html(You can uninstall the current one in your PC from the Control Panel)
After you download from the link above, double click it, and install it.
Then, right click the "Stencyl.bat" file, and select "edit" (this will open Notepad).
Change the
bold part like below.
java^ -Xms64m^
-Xmx4096m^ -XX:CompileCommand=exclude,javax/swing/text/GlyphView,getBreakSpot^
-XX:-OmitStackTraceInFastThrow^
-jar sw.jar
The first bold part "java^", this will use the JRE installed in your PC.
If you leave this untouched, it will use the Java in the Stencyl folder instead, located in "..\Stencyl\runtimes\jre-win\"
You can increase the second bold part,
4096 (4GB Ram) above if you need more.
Since you have 8GB, do not go more than 6GB (
6144), leave some to your Operating System.
Save the file.
And launch the .bat file.
Hope this helps.
Side Note :
You can just safely remove the _JAVA_OPTIONS environment variable.
Otherwise the method above will not work.
