Incompatibility of Logitech C300 Webcam to Windows 7

Hello Guys,
I changed my OS from Windows XP to Windows 7 and now that I want to install my Logitech C300 Webcam into windows 7, it keeps telling me that the program is blocked due to compatibility issues.
I checked online and follow the solutions that the logitech recommends but it did not work. Do I have to buy a new webcam? Does anyone know how solve this problem? Your comments and suggestions are very much appreciated.
Thank you.
Here is what happened every time I try to install Logitech webcam:
