iViewRED does not start

It is not sufficient to simply copy the

iViewRED

application directory to

another PC. You must use the

iViewRED

Installation package. This

ensures, for example, that the required Microsoft .NET Framework
Version 4.0 or above is installed properly.

You cannot start

iViewRED

from a network share /

network drive because of .NET security restrictions.

I am getting an error message

iViewRED

has several error states:

Not Connected

- This is indicated by the

in the application title

bar. Ensure that the

RED250mob ile Eye Tracker

is connected to the

USB port. If the

RED250mob ile Eye Tracker

is connected and you are

still getting a

Not Connected

status, the USB port may not be

functioning or you are using the wrong USB port (USB 2.0 instead of
USB 3.0 for example). In this case, ensure you are using the correct
USB port or try another USB port or disconnect any unneeded USB
devices.

Firmware Outdated

- This indicates that you need to download and

install the latest version of the software using the

Check for updates

link in the

Extras

tab of the
