Dear nolme,
Thanks for that information.
I also tested the scenario without a license file, so it is not the reason caused the issue. If you still get the LC.exe error after viewing the designer when rebuilding the project, I am afriad that now the solution is deleting the "licenses.licx" file in VS.
In addition, you can contact our sales team(
sales@e-iceblue.com) to get a temporary license file for one month to have a better evaluation on our products.
If there is any question, please let me know.
Sincerely,
Betsy
