Hi @chrisschaefer, thanks for the additional information…I shall pass your log data along to the developers. I wonder if the installer is incorrectly not finding MSVC2015, at least you have a workaround whilst we investigate the issue.
I found this link @ https://stackoverflow.com/questions/12206314/detect-if-visual-c-redistributable-for-visual-studio-2012-is-installed to help you confirm it is indeed properly installed. I am sure it must be (to be able to install older versions of Tobii Core SW) but still would be useful to know the results.
