A: You can configure Exe4j to use a different JDK by going to "Project" > "Settings" > "JDK" and selecting the JDK you want to use.
A: The main difference between 32-bit and 64-bit JDK is the amount of memory they can address. A 32-bit JDK can address up to 4 GB of memory, while a 64-bit JDK can address much larger amounts of memory.
Exe4j requires a 32-bit JDK to be installed on your system to work properly. The 32-bit JDK is necessary because Exe4j uses the 32-bit Java Virtual Machine (JVM) to run Java applications. If you have a 64-bit system, you may still need to install a 32-bit JDK to use Exe4j.
