| Problem | Solution | |---------|----------| | Exe launches but says "Can’t load IA 32-bit .dll" | You accidentally used 64-bit Java Home. Reconfigure with 32-bit JDK. | | Exe doesn’t start – “No JVM found” | Windows path or registry might list a 64-bit JRE first. Force the exact 32-bit path in exe4j. | | JDK 17+ 32-bit official builds are rare | Use JDK 11 or 8. For newer Java, compile to 32-bit via cross-compilation but test thoroughly. | | exe4j wizard shows “This JRE is 64-bit” warning | That’s a sanity check – ignore if you intentionally use 64-bit, but for 32-bit you need the opposite. |
Inside Exe4j:
Run your generated .exe from a Command Prompt without any JAVA_HOME overrides. Use a tool like (Sysinternals) to verify the java.exe process is running as 32‑bit (marked with *32 in Task Manager).
