Configure Launch4J to use 32-bit JVM only

Question

I\'m using Launch4J to start my Java application and if an x64 JRE is present on the system, Launch4J seems to prefer it.

Unfortunately my application cannot run on

Answer 1

This is an old question and Launch4J has been updated since it was asked. Now there is a dedicated user-interface control for selecting which version of the JVM to prefer. The options currently are:

• 64-bit only
• First 64-bit, then 32-bit
• First 32-bit, then 64-bit
• 32-bit only

The last, one of course, is exactly what the OP requested.

Answer 2

I have exactly the same problem : Into 64 bits environment if both 32 ans 64 bits JDK/JRE are installed this tools always detect the 64 bits version. I have patched the source (java + C++) code to make my own version and re-compile all. I add a check box to FORCE the 32 bits JDK/JRE detection into 64 bits windows environment. Just donwload the version and use it as the original one.

Version : launch4j-3.0.2-win32_Java32bitsDetection
