Thanks Halima and I have followed your advice but still have the same problems i.e DM shows a yellow question mark against the item, error code 28 and previously error code 1.
What I have noticed is that the webcam is listed in the category of "Other Devices" and showing as a "USB Camera". In DM there is no entry under "Imaging Devices" or "Sound Video and game controllers". Is that significant?
After downloading the latest software from the link provided for Webcam s/w, and letting the Hardware Update Wizard automatically install the drivers, the error message is;
"The hardware has not installed because the wizard cannot find the necessary software."
When I then try specific locations as mentioned in the article 929087, I get the same error message as above.
DM just does not seem to be able to locate the drivers.
One of the locations mentioned c:\Windows\Inf is not even listed in the \Windows tree structure, on his C:\ drive
Also the location c:\Program Files\Microsoft LifeCam\Driver32 cannot be selected unless you qualify this with \VX1000, and even then I am getting the same error message as above.
I would like to think that there is really something very basic that I am missing here, but now believe that perhaps there is a problem with the software download?
My friends PC is at the latest Service Pack 3 for XP and I also downloaded .Net framework at v4, before I did the software download. So I am pretty sure that I have done everything correctly.
Is the community able to offer any other suggestions?
I appreciate your time and input to my problem. Thanks
