不知道是哪里不对

Most probably you need 32 bit version (x86) of your Java

I think this is a launch4j configuration issue.
Ive tried with both 32 and 64 bit java of Oracle by setting JAVA_HOME environment variable.
The .exe doesn't attempt to look at JAVA_HOME and only relies on installed JRE/JDKs ( by reading certain windows registry entries ). I saw this in the process monitor tool.
.
I am however able to start this tool via the .jar using the 64bit Oracle JDK

This is with the 32bit one..

and its confirmed that this is a launch4j issue..
i ran the exe with the " --l4j-debug-all" flag to turn on launch4j debug logging..

in case this helps someone.. here's how I fixed this issue

• open registry editor
• add a new key "Java Runtime Environment" under HKLM\SOFTWARE\JavaSoft

•   ( if you don't have JavaSoft under HKLM\SOFTWARE, then you have to add that first )
  

• add a new String value for the above key , value name is "CurrentVersion" and value data is "1.8" ( this is if you want to use 1.8 jdk.. otherwise use 1.7"
• add a child "1.8" key under newly created HKLM\SOFTWARE\JavaSoft\Java Runtime Environment
• add String value in this key now, with name "JavaHome" and data "c:\path\to\1.8jdk"

This helped with the startup of luyten

there have not occured the java runtime environment error by executing your steps in regedit, thanks a lot! @sadaaithal
