Downloading and Installing Zep

System requirements

Zep runs on regular PCs under Linux (recommended) or Windows. Unless doing demanding graphics or sound processing Zep should run fine on any processor. For best performance we recommend a PC system with a quad core CPU, 1...4Gb working memory, an accelerated true-color graphics card with 1Gb of memory, and a 24 bit multichannel sound card.1) To use a button box with Zep your system should have a standard parallel port.2)

If this free software is useful to your research please consider a donation so we can keep supporting it free of charge:

Binary packages

The programs provided through the packages and installers listed below require a Pentium 4 (or newer) class CPU, so don't bother if your system was built before the year 2000. The 64-bit version obviously requires a 64-bit operating system.

Debian based Linux

The following packages are available for Debian/Ubuntu based Linux. Always prefer the latest version of Zep, unless you know you really need an older version. If you have a 64-bit OS then the *_amd64.deb package is for you, otherwise use the *_i386.deb package.

Attention! There is no SMI eye-tracker support under Linux. If you do wish to run an eye-tracking experiment under Linux using an SMI eye-tracker, then please give the vendor a nudge.

Download the desired package above and install it using the gdebi-gtk package installer or manually by running gdebi as in this example:

sudo gdebi zep_1.14.5_amd64.deb

or

sudo gdebi zep_1.14.5_i386.deb

If dependency problems are reported use the package manager to install the missing packages and try again.

The numbers that make up the version string represent a major version number, a minor version number and a patch level. Installing a Zep version which only differs in the patch level from one already installed will cause the one already present to be replaced. Versions that differ in the major and/or minor number will happily coexist.

Windows

The following installers where built for Windows 7 / Windows 8 (will likely work on XP and 10 too). Always prefer the latest version of Zep, unless you know you really need an older version. To install system-wide you should use the admin flavor of the installer.

Attention: Under Windows 7 the screen updates don't seem to be synchronized with the monitor's vertical blanking. This is probably due to the compositing Desktop Window Manager (DWM) used on that system. Under Windows 7 the DWM can be disabled; under Windows 8 this is not possible. Let us know if you have tested disabling the DWM.

Attention! From version 1.12 and higher the installer not requiring administrator rights is the one with nonadmin in its name. There is no Tobii or SMI eye-tracker support in the 64-bit version.

(for earlier versions please ask)

Download the desired installer above and run it. If the installer reports that the target folder already exists and you do want to reinstall, then run the uninstaller found in the mentioned target folder.

If your user profile has limited access to the PC your working on you may not be allowed to install Zep under C:\Program Files (or C:\Program Files (x86)) or register the application with the Windows Add or Remove Programs tool. If this is the case, you have to use the non-admin version of the installer.

It might be the case that running the downloaded installer by clicking on it is not allowed by your virus scanner. In this case just open a console window, cd to the folder containing the installer and run the installer manually. If that's not allowed either ask a your system administrator to install the application for you.

Optional additions

To improve the look of text presented on the screen we recommend installing the free DejaVu fonts. If present Zep will select the DejaVu fonts for its default Sans, Serif and Monospace font families. If the DejaVu fonts are not installed Zep will choose defaults which may not look that good or have a less complete Unicode coverage.

If you have any questions regarding Zep or suggestions for improvement please send an e-mail to theo.veenker@beexy.nl.

1)
Beware of on-board sound devices (incorporated onto the system's motherboard). These often demonstrate very poor sound quality. A typical symptom is hearing noise on disk access or mouse movement. You shouldn't use such systems for running listening experiments or other psycho-acoustic work.
2)
Under Linux this requires a kernel with hard real-time support via Xenomai. In Zep version 2 we will drop this for a more convenient solution. Parallel port support has not yet been implemented in the Windows version of Zep.
