Windows Install

To install ZS4 on Windows, just run the exe file after you have downloaded it.
Since v0.936 ZS4 can be installed wherever you like.

Linux Install

On Linux, extract the tar.gz file somewhere and launch the installer which is produced. The installation directory is t@b in your home folder.

Installation Remarks

Every new version gets its own subfolder (ex. 0.925) inside a .t@b/ folder.
Icons will be created on the desktop with the version number.

Uninstall Remarks

Under windows, since v0.936, an uninstall icon is provided in the startup menu
To uninstall ZS4 on Linux or with Windows v0.935 and earlier, just delete the t@b directory (or just the version folder) and kill the desktop icons. 
On Windows you can use the add/remove programs dialog to uninstall as of v0.936.

Using the Distro Package for Linux

There's a linux "distro" package for ZS4 available at http://devel.zs4.net/zs4distro_linux.html. This version is suitable for both: The integration of a zs4 install within a larger install (like a linux distro) and the installation of ZS4 for linux when other means have failed.
