Same issue here.
I had installed a previous version of the driver (used several versions from when it was free), decided to play with 2 cams, PAY and download SDK 1.6.2.0028; Install it over previous driver ... keeps showing only 1 camera, uninstall camera drivers and SDK; Install SDK ... no driver present -try multiple combination of uninstall plug/unplug instal plug/unplug, none work-
After install I only have the Device manager in C:\Program Files and the samples in $User\Code Labratories, no trace of the driver
(samples fail saying no PS3 camera)
System: Windows XP sp3, updated, interned connection ok, ping to codelaboratories ok ... Previous driver was working ok.
Edit: Try to install in another computer : Win7, updated, etc .. same result
Edit: Solved : I get in contact with CL support and they provide me a link for the driver
