I lost driver for web cam ITSG and I Can´t istal it

Go to the support website for your camera, look for the software support, I have done this a few times and always found the software I needed.

Well, try googleing for drivers on your specific device. get the model number for the web cam (should be on the device) and type it in the search bar as: Model #: XXXXXXX Drivers for Windows XP or whatever operating system you have.
