Install the software. Yes, it gives an error "You cannot use the current version blah blah blah". HOWEVER, setup extracts the drivers to the following directory:
C:\Program Files (x86)\Labtec\WebCamWebInstall\Drivers\x64
[Comment] Normal unistall -procedure shouldn't leave any files behind, but Labtec's does (fortunately).
Now open the Device manager. Choose your webcam. And if you don't know which one of the devices is your webcam, you should try to find ? -sign and if you check the hardware details, you should be able to find the USB hardware id. Hardware ID for my webcam (same as yours) should be USB\VID_046D&PID_08A2&REV_0100&MI_00
Choose the device. Click the mouse's right buttom. Choose Update the driver software. Locate the driver. You can find the driver from directory: C:\Program Files (x86)\Labtec\WebCamWebInstall\Drivers\x64 or similar... depending the OS version you have.
There are also two subdirectories ...\WELH64 and ...\WIM64
Your driver is in ..\WELH64 -subdirectory, if you have models Labtec WebCam(Elch 2) / Lacamus, Labtec webcam plus
Your driver is in ..\WIM64 -subdirectory, if you have models Labtec Webcam Plus, Labtec notebook webcam, Labtec Webcam pro.
In your case choose the ..\WIM64 -directory, press ok, and it should find the driver. Voila.
And these instructions should work also for combinations: Windows 7 & Labtec WebCam(Elch 2), Lacamus, Labtec webcam plus, Labtec Webcam Plus, Labtec notebook webcam, Labtec Webcam pro
