USB Webcam PC camera VIMICRO V not working on Dell D800 laptop

I am using Dell D800 laptop and since the intervention of a technician (probably black screen) I can not use my USB Webcam PC camera VIMICRO V. If I want to remove the program I have:
> setupDLL / setupDLL.cpp (439)
PAPP: VIMICRO USB PC Camera V
PVENDOR: VIMICRO Corporation
@ Windows XP Service Pack 3 (2600) IE 7.0.6000.16827
and if I reinstall the CD of the webcam, he asks me the CD


Can anyone help me ?

Thanks

Check the manufacturer's site to find the drivers for your webcam (it's integrated webcam).

This is not an integrated web cam. I do not understand because before troubleshooting my PC, the web cam VIMICRO (CD training) worked very well.

Clean the registry with CCleaner and restart the machine before restarting the installation. Do not connect the device once the installation is complete or when it is requested by the installation program, not before.
