Make sure the user installing hardware is an administrator.
I recently purchased an HP Compaq L2105tm touch screen monitor for my Dell Inspirion 1545 laptop running Windows 7 Home Premium 64-bit.
I have no problems getting a picture through VGA hookup. When I plug in the USB for the touch I get a notice that Windows is installing drivers and that it completed successfully and yet I don't have any touch capability.
HP website and drivers say that no drivers are needed on Win 7, that they use native drivers.
Called up HP tech support and they said the problems is on Dell's side, that Win 7 should have everything needed to make this work.
Called Dell up, rep remotely viewed my computer and told me they had a solution for $129 which I declined.
I spent over 3 hrs yesterday googling and reading forums for solutions to no avail.
I hooked up this monitor to my father's Dell desktop running Win XP and had no problems, great picture and full touch capability.
Any Ideas?
Thanks

I am, I'm the only one using this laptop and I don't have any other users/identities on it.

Even with that UAC can kick in for some very funny behavior, try hooking it up with UAC off. You do have the various touch/tablet interface components on via the additional features?
The XP test only tells you the hardware is good, Win7 is a completely different beast in the way devices and drivers install.
Dumb afterthought.. you are doing this with an AC adapter and not on battery, right?

OK, turned UAC off, went and uninstalled all HID drivers in device manager (I can get around with keyboard just fine ;) ). Shut down, rebooted (with usb cable inserted for touch), all drivers loaded, still no touch. TACTION was installed under HID, Pen and Touch is available in Control Panel; 'Use your finger as an input device' is checked and still no touch. :(
And yes, I'm doing all this on AC power, and have been doing so since I got monitor.
