Thank you for your response.
I have done the manipulation of the link above.
I have a reboot and activate my UAC at (default) level
But the worry is still there.
I'll try to be more specific.
Bandicam freezes when the program installation is running.
When I want to take a video of the installation of a program bandicam freezes 6 to 8 seconds after allowing user account control to run the program I want to take a video of. I remind you that I didn't have this problem with the free version of Bandicam.
Once this program is installed I can use bandiacam to film actions on the program in question.
I repeat again that if the UAC is disabled I don't have this problem.
Sorry for all these messages but having bought Bandicam to take full advantage of it, I would like it to work better than the free version.
