    I am developing an interactive C++ application (a game) which is supposed to use the Tobii 4C eye tracker. In order to interface with the eye tracker, I am using the Stream Engine API.

    Stream engine api link (download link at the bottom of page): https://developer.tobii.com/consumer-eye-trackers/stream-engine/getting-started/

    I added the .h files provided with the API to my project and I added the directory containing the tobii_stream_engine.dll and tobii_stream_engine.lib files to the project library directories.

    My issue is that I am getting a LK1107 error (invalid or corrupt file) on thetobii_stream_engine.dll file at the linking stage (not a runtime error). Personally, I think this is a binary compatibility issue as I am using the 2019 MSVC toolset.

    Do you have any input?

    Thank you,

    Hi @davidolivier, sorry to hear about your issues. Could you kindly confirm which Visual Studio version you are using? If not already, we recommend 2019. Have you tried (as a test) both the 32 and 64 bit versions?

    If you have a spare system to test that would also be useful as the files themselves have been checked for consistency. I assume that you already tried downloading again , perhaps with a download manager to ensure no lost packets.

    Hopefully we will get you up and running soon, thanks for your patience.

    Hello again,

    I ended up solving the issue by following the steps in the following tutorial (for future reference):

    Essentially, I was missing one step : copying the provided .dll next to the executable .exe in my build folder (as recommended in the tutorial). I come from a linux background … I still have to work on my windows devops skills I guess.

    Thanks for the quick response!
