XP won't capture pictures

Look in My Computer.
If you see the camera listed, right click on it and remove it.
Look in Device Manager.
(right click My Computer, select Properties, click the Hardware tab and then the Device Manager button)
Look under Imaging Devices if present and other related directories.
If you find a listing for the camera, right click on it and select Uninstall.

Reboot.

Once back up, plug in the camera and answer yes and OK to any questions that may come up from the Add New Hardware wizard.

Hope this works for ya.

Try the "Questions" forum; the "Discussion" forum is for matters of general discussion, not specific problems in search of a solution.

Post problems such as this to the "Question" forum, rather than the "Discussion" forum. There are those who specifically seek out problems in need of a solution, and that's where they go to look for such.

Additionally there are the benefits that:

1) The "Questions" forum provides for your feedback, by way of your being able to mark "helpful" responses as such. This does not necessarily mean that a given response contained the complete solution to your problem, but only that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours, so that they might have a ready source of reference available, thereby perhaps obviating the need for them to repeat questions previously asked and answered.

2) The revised TR makes it quite difficult to find both "Discussions" and "Questions" that have not had a fairly recent post, owing to some functions comingling them in the listings. By keeping each type in their respective forums, it is easier for all to find what they are looking for.
