I am trying to install an Argus USB Digital Still Camera that I have bought but am getting some kind of message that says "An error occurred during the installation of the device. The class installer has denied the request to install or upgrade this device". I have used this camera on different computers with Windows XP and am still getting the same error. I have also tried to delete the registry key in HKLM\System\CS001\Enum\USB and then restarted the pc, but still it wont work for me. Any ideas?
