Hi @sapp, sorry to hear about your issues. Can you kindly confirm for us what happens if you follow our WPF Guide @ https://tobiitech.github.io/interaction-library-docs/wpf/html/index.html
You should only need to unzip the Interaction Library ZIP and use the Visual Studio Developer Prompt command to get the program running:
msbuild samples/wpf/Tobii.InteractionLib.Wpf.SampleApp/Tobii.InteractionLib.Wpf.SampleApp.csproj /p:Configuration=Release /p:Platform=x64 /verbosity:minimal
Which produces the relevant exe. I had to first install the Microsoft .NET Framework 4.7.1 Developer Pack available @ https://www.microsoft.com/en-us/download/confirmation.aspx?id=56119
Please let us know the output from this command. Best Wishes.
