Hi LilDark,


Thank you for posting in the Microsoft Community.


I would suggest you to download then install the Sony ArcSoft WebCam Companion 4 driver in “Compatibility Mode” and then check if this fixes the issue.


Follow these steps to install in Windows 7 Compatibility mode:


Step 1: Uninstall the webcam driver from “Device Manager”.


a.       Press “Windows key + W” from the keyboard.

b.      Type “Device Manager” without quotes in the search box and hit Enter.

c.       Search for “Webcam” from the list of devices.

d.      Right click on your “Webcam” and then select “Uninstall”.

e.      Restart the computer for changes to take effect.


Step 2: Install the driver in “Compatibility mode”


a.           Download the “Sony ArcSoft WebCam Companion 4 driver” from the manufacturer’s website and save it on your local disk.

b.           Right click on the driver setup file and select “Properties”.

c.            Select “Compatibility” Tab.

d.           Make a check mark next to Run this program in “Compatibility mode” and select previous version of Windows supported by the software, from the drop down list.

e.           Then click on “Apply” and “Ok” option.

f.            Then install the driver.

g.           Then restart your computer and check how it works.
