If there are no Windows 7 drivers available, I'd suggest you installing the Vista driver in Compatibility mode.
Follow the steps below to install this software in Windows VISTA SP1 Compatibility mode:
a. Right click on the setup file.
b. Go to properties.
c. Click on Compatibility mode.
d. Place a check mark the box in the box in front of “Run this program in compatibility mode for” and from the drop down menu choose Windows Vista SP1.
e. Place a check mark on "Run as an Administrator" under privileges level and click on apply and then Ok.
f. Now double click on the setup file to initiate the install.
You may also check the make of the camera in the device manager and download the drivers from the webcam manufacturer's website directly.
