JDK 5.0 or newer cannot be found on your machine.

That’s because a JDK or Java Development Kit is not installed on your computer. If your program works properly when you are using your laptop and not if you’re on your desktop computer, it means a version of Java Development Kit is installed on your laptop but not on your desktop computer.

If you want to make your program work on your desktop computer as well, you need to install Java Development Kit. To download the latest JDK for Microsoft Windows, go to Java SE Development Kit download page and download the version for your operating system. The latest version at the moment is available only in 64-bit version.

Before downloading, please take time to read Oracle’s license update on Java Development Kit.
