Hi

I am attempting to install a USB digital camera but I am getting problems. There are two portions of the driver installation, one for the video (this enables you to use the camera as a webcam)and one for the digital camera itself so that you can download the pics. The installation of the main driver seems to go OK but when you install the video portion, I get the following message near the end of the installation "cannot install, an error has occured, the class installer has denied the request to install or upgrade this device". What does this mean? I have made sure that I am using the latest driver, I would really appreciate if anyone could advise on how to resolve this issue because I need to use this camara urgently.

Thanks for all you help in advance

Cheers

Roy

Who manufactures the model you purchased? Can you get their technical support help? Have you followed the instructions in the manual step-by-step.

Generally with USB device, you connect them and they install. With cameras you need to installthe driver first, then connect the device when prompted to do so. Have you install that way?

What are your video card specifications. Does the camera come with Windows XP specific drivers?

The error "cannot install, an error has occured, the class installer has denied the request to install or upgrade this device" indicates that the driver may already be installed.

I hope you created a restore point in WinXP before this installation... that's always a good idea before installing USB devices... if so restore back to it. If not, then go to Control Panel --> Add/Remove Porgrams and remove all programs associated with the camera. Then Shutdown all the way and then power thecomputer back up (to make sure that the system is operating under the newly revised registry). Then start the install over step-by-step if the camera software requirements are meet or exceeded by your system, and if you have WinXP specific drivers for this device from the manufacturer.
