I have a problem with Java on my Windows 8.1. The problem is that programs work with either 32-bit or 64-bit version of Java, but not with both.

So, when some program work with 32-bit version, I have to reinstall that. If some other program works with 64-bit, again I have to reinstall that. But again, if some other program requires 32-bit version, I have to reinstall that version.

In other words, I cannot use two programs which require two different versions of Java at the same time.

What is the proper way to overcome this issue?

  • Install both and switch as needed. See [so] question [Switch between 32-bit and 64-bit JDK platform on Windows 7](http://stackoverflow.com/q/16949091) – DavidPostill Sep 16 '15 at 11:02
  • So, you are suggesting me to set Java path in IDE (if it's an IDE), od change system PATH variable manually each time when I need to start some Java based application. I've already known that. I was hopping there is some more practical solution. But thanks, anyway. – Elvedin Hamzagic Sep 16 '15 at 11:17
  • Yes. Don't forget to change JAVA_HOME as well. You can do this in a batch file ... – DavidPostill Sep 16 '15 at 11:18
  • For JAVA_HOME I can do that in batch file, but for PATH I cannot. At least unless I make some utility app for that. – Elvedin Hamzagic Sep 16 '15 at 11:24
  • You can set the path as well in a batch file. See [What are PATH and other environment variables, and how can I set or use them?](http://superuser.com/q/284342) – DavidPostill Sep 16 '15 at 11:28
