It is also possible that the camera software needs a newer version of drivers installed for your mother board. Jenoptik should be able to tell you if the drivers need to be updated.
If you want to try updating your mother board drivers, you first have to determine who made the mother board, or what chipset is on the mother board.
If your computer is a major brand, just go to the manufactures website, download, and install any driver updates that they have posted for your computer.
If it is not a major brand, check your documentation for information on the mother board.
The make and model of the mother board may also appear on the screen when you first turn on your computer.
Once you have the mother board identified, go to the board manufactures web site, and get the latest drivers posted there.
