2) .kada pokrenes instaler, i kada ti izbaci poruku o gresci,nemoj zatvarati taj prozor, vec ga ostavi otvorenog. zatim idi do foldera Temp folder gde je otpakovan drajver (u XP je C:\Documents and Settings\{username}\Local Settings\Temp\QuickCam_11.1.0) COPY (ne Move) this folder to a location that's accessible to your Windows 7 system.
3a) For Cisco VT users, go into the \QuickCam_11.1.0\Drivers\x64\PRO464 folder and edit the lPRO464v.ini file. Do a find-and-replace, finding 08C5 and replacing it with 08C7 (this essentially makes the ini file identify your Cisco VT device ID as a QCP 5000). Save and close the ini file.
3b) Go into Devices and Printers. Go into the properties for the USB Composite Device, find the Unknown Composite Device, and update the driver. Select to manually specify the driver location. Point it to the \QuickCam_11.1.0\Drivers\x64\PRO464 folder, and you should be all set.
