Hi Terry and welcome to the Q&A Board. There are a few things that might cause the problem but if you're getting a specific error message when you try to upload your images it would help us to know. According to HP the camera is compatible with ME so we'll skip that possibility. The HP site indicates that this type of problem can also occur if you have another HP device attached to you PC (driver conflict). As a starting point check out this
link from HP. Please get back to us with any other specifics if this doesnt work and we'll try to help you through it.
