You need the Win7 camera driver, check sony support at:

just enter your Win7 operating system (there are 9 versions of Win7), and select the downloads (2)
for your computer camera driver.

Versions of microsoft Win7 - determine which yours is by (these instructions are for WinXP);

START > Control Panel > System > General (tab)

Windows 7 Professional 64-bit
Windows 7 Starter 32-bit
Windows 7 Ultimate 32-bit
Windows 7 Ultimate 64-bit

SONY is like that you may have to get the update driver form SONY for that unit

i assume you upgraded the operating system to windows 7 ultimate using a retail copy of disc.
vgnfj270/b only supports windows xp and vista home basic.

• this model of vaio doesnt have a camera driver and software for windows 7 ultimate. check this link

esupport.sony.com

Windows 7 requires the drivers be updated or at least compatible with Windows 7....so if Sony has not written the drivers for your machine yet, they probably won't and those devices will not work under Win-7.

If you call Sony's customer service or support line and complain to them, they may provide you with a work-around that will get them back operational again.

good luck

First find your VAIO Camera capture utility and configure it to see both your webcam and your microphone/ to do this if VAIO Camera Capture Utility is not in your start list of programs, Click on start in the space search "VAIO Camera" without the quotes. it should bring up the VAIO camera capture utility. Click on it/when it opens click on settings/ click on the Cam/mic tab and choose Sony Visual Communications Camera in the drop down under preferred Camera/ Do the same for your Preferred Microphone/ click OK/Now click the little red x in the far upper right of the VAIO Camera Capture utility to close it. Now in your chat software either Windows live chat or Yahoo chat or whichever one you have. I have Windows live chat/ configure your video in there as well to use your motion eye and your microphone. You should now be able to chat live seeing and hearing your guest as long as they have the same chat program.Do a search on google for "Windows Live Messenger" if you wish to use that utility to chat with. If you choose Windows Live Messenger, in the main window click on tools/ click on "Audio and Video Setup".

Did u install any other programs anfter your vista instalation? try to uninstall them one by one, My guess is that one of the programs "kidnaped" you camera. By uninstaling one by one you can easy find out witch one it is. After uninstalling one program test your camera. If it works again you that program is the problem.

Good luck

I have windows vista sony vaio vgn fe880e buying at america, but I dont have drivers of motion eye web camera

Windows Vista is not the greatest at working on proprietary machines with drivers intended for XP. Can you get a driver from SONY for the motion eye that supports VISTA? I had Vista on my new machine (Dell) for all of 3 minutes before I uninstalled it and put a brand new copy of XP on. It's stable -- and works. Vista is squirrelly.
