exe4j Wizard - 32-bit or 64-bit | ![]() ![]() ![]() |
On Windows, a native executable can be either a 32-bit or a 64-bit executable. If you need a 64-bit JRE for your application you can choose to generate a 64-bit executable.
Note that it is not possible to create launchers that work with both 64-bit and 32-bit JREs. Since the launcher starts the JVM with the JNI interface by loading the JVM DLL, the architecture has to be the same. If you target both 32-bit and 64-bit JREs and operating systems, you have to generate different executables for them.
On a 64-bit Windows, there are separate system directories for 32-bit and 64-bit applications. If you enable the 64-bit executable mode in this step, those system directories will be appropriate for 64-bit applications, e.g. c:\Program Files instead of c:\Program Files (x86).
