Recently, i have downloaded the JT open Toolkit. I installed it according to the Siemens Guidance and then Firstly i tried to follow the Get_Started_Doc in the Program and wanted to open the Geom_Simple Example. After i did so and also gave my Sold_To_ID, i tried to run the app, but i got some weird Errors as below :
If the sample project file is compiling successfully and you have an executable you probably have some issues in the environment. Take the .exe file and drop it in the lib directory for your platform and see if it runs from there.
