There are four things to check on when deploying a Unity application, especially for a public display:

1. The drivers are installed
2. It has the appropriate dll's next to the exe
3. It can find a calibration file
4. It runs the right version on startup

And if you are doing this more than a few times, then to start looking into getting an installer made.

Driver

The driver and driver installer is included in every installer on the eyetech's support page:

DLLs

Unity eye tracking games require:

• QuickLink2.dll - always required for all EyeTech eye tracker models
• SMX11MX.dll - VT2, VT2 Mini and TM4 Mini models
• PGRFlyCapture.dll - TM3 or TM4 models
• pgrflycapturegui.dll - TM3 or TM4 models

These dll's need to be copied and present right next to the exe in the install folder.

Calibration

A calibration will probably be searched for in:C:/ProgamData/EyeTechDS/QLCalibration_Default_User.cal

Some versions may look for the .cal file right next to the exe, too.

To update the stock calibration file, use a program like Quick Glance or QuickACCESS, to create a new one. Both of them create them somewhere under the C:/ProgramData/EyeTechDS folder structure.

Startup Folder

To launch it on startup, from the Start Menu or the Windows Metro/App screen type shell:startup and press enter. This will show a folder with the path of C:Users<username>AppDataRoamingMicrosoftWindowsStart MenuProgramsStartup. Remove any old shortcuts for the Unity game here, and replace it with a shortcut to the exe with the most up-to-date version.

Installer

An NSIS installer can do all of the above tasks given time and testing. Request for an installer, and engineering time can be allocated to it.
