|"hp webcam not working windows 7"|
You specified Windows XP below your user name, and you mentioned only XP in your post.
Where to un-install improperly installed software in the following has the location for that in Windows 7.
In XP, that's at Control Panel - Classic view - Add or Remove Programs
Whatever software you install for the webcam must be for the operating system you're using it in.
All versions of XP except Pro 64 bit are 32 bit (x86).
Windows 7 can be either 32 bit (x86), or 64 bit.
I'm assuming it's an external webcam connected to a USB port.
If it's built into your computer, the same as in the following applies regarding installing the software for the device properly otherwise.
You may need to plug it into a DIFFERENT USB port, or use a different USB cable,
or, rarely, if you have a desktop computer, if you have cards installed in mboard slots, you may have an IRQ sharing problem you need to fix.
Troubleshooting USB device problems
See Response 1:
Other than that, the most common reason for a USB connected device not working properly is you DID NOT install the software for it properly !
You MUST install the software for it properly. Follow the installation directions in the webcam model's MANUAL. If there are two manuals, the installation directions may be only in one of them.
If you have the CD or DVD for the webcam, the manual(s) is(are) probably on that If you don't have the disk, the manual(s) are probably available on the manufacturer's web site in the support for the specific webcam model. .
E.g. these things are universal for most sophisticated USB devices....
DO NOT plug in the USB cable to the device BEFORE you have installed the software for the device, unless the installation directions tell you otherwise
DO NOT point Windows to where drivers are when Found New Hardware pops up for the device BEFORE the software for the device has been installed, unless the installation directions tell you otherwise.
More sophisticated devices always have associated software that must be installed properly along with the actual drivers.
Installing only the actual drivers does not install that associated software properly..
If you DID NOT install the software properly according to the installation directions, go to Control Panel - display as Small icons or Large icons - Programs and Features
and un-install ALL entries for the software for the device, BEFORE you install the software for it the proper way.
(if the webcam is built into your brand name computer.......
- the proper software instillation file is probably available in the downloads for your specific model on the brand name's web site. In some cases the model came with a CD or DVD with the proper software installation program on it.
- if there are no installation directions at the same place you get the proper download, or on the CD or DVD that came with the model, assume that you DO NOT point Windows to where drivers are (e.g. where the download is, or where the result of extracting the download is), when Found New Hardware pops up for the webcam, BEFORE you install the software for the webcam.
- if you suspect you may have installed the software the wrong way, un-install it in Programs and Features BEFORE you install it again. )
