for FREE

Most programs typically come with everything included, but you may still need to have some prerequisites installed. We’re all too familiar with needing a certain .NET Framework version, and the same is true for Java-based programs.

A lot of the appeal of portable software is that it doesn’t need to be installed, so naturally, you’ll want to put them on a USB stick and use them freely on any system. If the respective program needs Java, then including jPortable on the same stick can save you from having to worry about having this important runtime.

As stated earlier, this solution seeks to address any potential problems users may encounter with portable apps that require Java. By including and running this on a portable drive, users can avoid issues that pertain to Java runtime compatibility. It's worth noting that compatibility with PortableApps software is automatic.

Most importantly, this means that you do not need to have a Java runtime installed on your local machine. There’s no need for admin rights to get everything to work, which is all the more convenient on portable storage.

The user-program interaction is minimal in operating this solution. Running it will automatically create a CommonFiles folder, which will then be recognized by any portable app installed on that specific drive. As such, there’s no need to relocate any files or folders around.

As it stands, jPortable manages to ensure Java runtime compatibility for portable apps that depend on it. The software’s portable nature adds to the convenience factor, and as such, the need to have Java on the local machine installed is no longer something to worry about.
