Download links

More detailed instructions are below, but if you know what you're doing, download the appropriate file for your operating system:

Windows installer
MacOS disk image
Linux installer (64-bit)

Windows downloads

Windows installer

Instructions (installer version):

1. Download the installer, and run it.
2. Open "Launch Scythebill" inside the new Scythebill shortcut in the Start menu (or double-click on any existing .bsxm sightings file)

Many thanks to BitRock for making their installers freely available for open-source software.

MacOS downloads

​MacOS disk image 

Instructions:

1. Download and open the above .dmg file.
2. Open the now-available Scythebill 13.9.4 disk, and drag Scythebill from it into your Applications folder.
3. Open Scythebill (from your Applications folder)

Scythebill now requires MacOS 10.7 (Lion) or newer - which covers all versions of MacOS back to 2011.

Linux downloads

Linux installer (64-bit) 

Instructions:

1. Download the installer
2. Open a terminal, and type:
   chmod u+x ~/Downloads/Scythebill-13.9.4-linux-x64-installer.run; ~/Downloads/Scythebill-13.9.4-linux-x64-installer.run
3. Run Scythebill with ~/Scythebill/Scythebill.run

Scythebill also (for now) supports 32-bit Linux, with a 32-bit Linux installer.  32-bit Linux is not going to be supported for much longer, though - we strongly recommend upgrading to 64 bit.  To install this version:

1. Download the installer
2. Open a terminal, and type:
   chmod u+x ~/Downloads/Scythebill-13.9.4-linux-installer.run; ~/Downloads/Scythebill-13.9.4-linux-installer.run
3. Run Scythebill with ~/Scythebill/Scythebill.run

​Cross-platform JAR

Cross-platform JAR

You can use this file to run Scythebill on any operating system, but it requires a Java installation, and is missing many of the niceties of the native applications above.
​
Instructions:

1. Download the .zip file and unzip into a JAR file
2. Install Java (Java 8) or later
3. Open the JAR file (or run from a terminal with "java -jar scythebill-13.9.4.jar")
