Unfortunately, Labtec webcams are developed to work only with Windows XP and below operating systems. If you're using a newer Windows platform, you can try to install the files using the Compatibility Mode. Right click on the installation package and go to Properties > Compatibility tab. Check the Run this program in compatibility mode for box and select Windows XP or a compatible operating system from the drop-down list. Click Apply and then OK. After that, right-click again on the installer and select Run as Administrator. If it doesn't work, you can try to find the compatible drivers using Google search engine or a driver identifier from Software Informer database.
