Installing Standalone eHour 1.0
For every supported operating system the installation steps are the same, first install Java and then download and run the appropriate eHour installer for your operating system.
Download and install Java
The Java runtime environment is not bundled with eHour. When Java is not installed, download and install the latest JRE from Oracle's site
For Windows there is a separate 32-bit and 64-bit eHour download. The version must match the Java environment installed - when you installed a 32-bit Java environment on a 64-bit Windows OS you need to download the 32-bit eHour download. Nowadays it's most likely that you run a 64-bit version of Java, Windows and thus eHour.
