Since the copied 'jre' is justed copied, not normally installed by JRE's install file, other softwares cannot find it, so this copied 'jre' is a private JRE and used by your generated exe only. You can pack the 'jre' directory and your generated exe file into one install file, and let the 'jre' be extracted with your main exe file into the same directory. The 'jre' directory need not to be INSTALLED, but just a COPIED 'jre' directory will work. When a 'jre' directory exists along with generated exe in the same directory, the generated exe will use the 'jre' directory first.

How to run generated exe on a computer without JRE installed? (While if the binary code depends on the runtime library, the size can reduce to 20kb ~ 100kb, but less compatibility.) The independency of runtime library brings a good compatibility, but it lets the size of exe file a little larger, that the binary code is about 150kb ~ 300kb according the options. The binary code of generated exe files does not depend on MFC, STL, or VC runtime library on Windows, does not depend on GLIBC on Linux. Jar2Exe does not compile java code into native code. When a generated exe file runs, it starts the JVM and call the main method of entry point class. Jar2Exe generate exe file by wrapping binary code around encrypted jar file.
