Now that is strange as you still find the issue and we do not find your issue using your exact sample project with your license file. Please open the generated Excel file into MS Excel we attached in the previous reply. Do you see any issue with it?
Do you mean you get evaluation warning exception or you get evaluation warning sheet in your output Excel file? If you do get evaluation warning (exception) message, give us the exact message. Even I just added a line:
//Check if license is set.
Console.WriteLine("Licesee is set: " + ExcelFileWorkbook.IsLicensed);
to your code, recompile and run it. It works fine and license is set properly as per the console output. The output file has no evaluation worksheet. Also, there is no evaluation warning while running the code. See the screenshot attached to get console output display when running your project.

I guess you are not using the exact project and license file you shared with us via private message(s). Or your original project is different. For confirmation, please extract the same “TestAspose.zip” archive (you shared via private message) into some file path. Now open the “TestAspose.sln” into your VS.NET and run it (you may embed the line as I suggested above to check if license is set or not). Please capture the screens (while running the project) to create a demo video to capture everything, zip the video and share it here. Also, share your output Excel file with us. We will check it soon.
