Howto Install HelloNzb

HelloNzb is written in Java, so it runs on many platforms. It was developed and tested on Windows and Linux systems, but it should also run fine on a Mac and other platforms. Please let us know of any bugs!

To run HelloNzb you need the JRE (Java Runtine Environment) in version 1.8.x or later installed on your computer. If you haven’t installed it yet, you can download it for free from the Oracle Homepage. If you are using Linux then you might want to install Java via your distribution’s software installation tool.

  • If you want to use the automatic PAR2 check & repair feature of HelloNzb, you need to download the free PAR2 command line utility for your platform. You can grab it from our Tools folder (Windows only), or from here (official mirror, look for”par2cmdline”).
  • If you want to use the automatic RAR archive extraction feature of HelloNzb, you need to download the free Unrar command line utility for your platform. You can grab it from our Tools folder (Windows only), or from here (official mirror, look for “Command line freeware”).

Download HelloNzb

You can download the latest version of HelloNzb from the sourceforge.net project page.

Microsoft Windows (XP, Vista, 7, 8)

For a Windows system you can download the packaged Win-release of HelloNzb (named “HelloNzb.exe”). This version of HelloNzb is an executable Win32 file that you can run by double-clicking on it like any other Windows program. Please note that you need to have a JRE installed in this case too!

Linux/*BSD/Unix/etc.

On Linux- and Unix-based systems you will probably want to download the .jar version of HelloNzb. After you have downloaded it to a folder of your choice you can run HelloNzb with the following command (be sure to have the “java” executable within your PATH system variable):

shell$ java -jar /path/to/HelloNzb.jar

Note that if you want to download large files or archives with HelloNzb, then you might need to increase the amount of memory reserverd by the Java virtual machine. You can do so via the following command, where the first argument specifies the min. amount and the second argument the max. amount of memory used by HelloNzb:

shell$ java -Xms128M -Xmx512M -jar /path/to/HelloNzb.jar

Of course you can also add a shortcut to this command on your desktop!

Other platforms (not tested yet)

If you’re using another platform then you can also try the .jar release of HelloNzb, like under Linux. Or you can download the HelloNzb sources and compile them for yourself.
