Re: paid license expired (General questions)
The bad part is, distributed application has also to be run as administrator, I run the app.exe on same computer and it crashed.
Please suggest a solution.
Rahul,
There's no difference in functionalities between the .dll and .ocx, apart from the .ocx having a GUI.
As for the .ocx not working on Vista / Win7, I don't see why it wouldn't work. The only imperative is that you run your development environment with Admin privileges when placing the control on the form. Also, registering the .ocx / .dll needs to be done with admin privileges as well.
I'm not sure what other issues you had, but you can always contact us for help.
