Troubleshooting
Installation
Incompatible program version
When downloading the program, ensure you are using a compatible version with your operating system. Windows and Apple Mac require different versions. All downloads are available at eyeprecision.com/downloads
Older Macs with an intel chip require a different version. This is also provided at eyeprecision.com/downloads
To check if you have an Intel or Silicon chip, click on the Apple symbol at the top left of your screen, then select "About This Mac"
License Keys
After installing the program, you will be asked to enter your license key. This is a 16-character code that was provided to you when you purchased the software
Make sure to enter the license key exactly as it was provided, including any dashes or capital letters
If you are copying and pasting the license key, ensure that there are no extra spaces before or after the key
Each Eye Precision program (Eye Precision, EP Animations, EP Latencies) has its own license key. so ensure that you are entering the correct license key for the correct program
If you are having trouble with your license key, please contact our support team at support@eyeprecision.com

Purchasing updates
There is no need to purchase updates. Updates are provided free of charge to all users. The initial license is valid for the lifetime of the software

Head Position Tracking not available
Head Position Tracking is only applicable in Smartphone mode
When in Goggles or Nystagmus mode, the Head Position Tracking selector will be 'greyed out'
The current mode is displayed next to the Head Position Tracking selector. To change modes, go to the menu at the top of the window (Windows) or screen (Apple)
Loading previous results
To load past analyses, click on the "Load Previous Results" button. This will show directories in the Output Directory
Select the folder containing the results you want to view and click "Select Folder" (Windows) or "Open" (Apple)
Do not double click on the folder, as this will show the contents of the folder, not load the results themselves
Pupil tracking failing
This can have many different reasons in many different scenarios

Video playback not working/slow
Eye Precision offers two different way to playback videos in the results view - the inbuilt player or VLC media player
In general I'd advise using VLC media player for the best performance. This requires VLC to be correctly installed on your computer
You can download VLC from videolan.org/vlc
To choose a media player, go to the menu at the top of the window (Windows) or screen (Apple)
