Hi dnosoluk and welcome.
This is a long standing problem with Vista. We have reported it to Sony but are still waiting for a solution.
There is a solution which is to disable Vista’s 'User Account Control' – you know the thing that keeps popping up annoying messages saying “Are you sure you really want to open that program”.
However, this may make your Vaio less secure so try these two things first which do work for some users: -
1. Install Microsoft Hotfix KB931812 which is specifically for this problem. However, it will not install on everyone's vaio
2. The camera appears to work 'once per session' and will work with only the first application opened. You should be able to re-boot and use another application - but check Skype does not open automatically at startup and grab the camera.
If these don’t fix it the only solution I know of is to disable Vista’s UAC. I should point out that UAC is a security feature incorporated into Vista and disabling this may make your Vaio less secure. This has to be your choice but it will probably fix the camera!
To disable User Account Control: -
Press the Windows key on the left of your keyboard and press R
Type in the command
MSCONFIG
and press OK -> Continue.
Open the Tab “Tools” and scroll down to ‘Disable UAC’ and click Launch. At the black screen, click OK and restart your Vaio.
