Windows 7 - Canon camera recognized on USB, but not AutoPlay

I have two HP laptops and a Canon SX130is digital camera. I am not using Canon's camera software -- I just want to download photos. Both computers are running Windows 7-64. Both are Home Premium Versions.

On my HP Envy, USB recognizes, the camera, AutoPlay opens so I can select my action and I can also browse the memory card in Windows Explorer.

On my HP DM4, USB recognizes the camera, but no AutoPlay on any USB port. SD memory cards and flash drives open AutoPlay, so the issue is about the camera on one computer.

I have checked the AutoPlay settings, run net start shellhwdetect and the results are the same.

Can anyone offer a direction for me to take to fix this issue on my DM4?

Thanks,

Doug

In Windows 7, type "autoplay" (no quotes) at the start button. Make sure "use autoplay for all media and devices" is selected.

Alternately, (I believe) you can hold down the shift key when inserting your usb device, to override and get autoplay to work.
