Not sure what IE7 has to do with the problem.
When you insert the HP Printer software CD, does it register in My Computer? If so, right click that drive select "Properties", then in the new window goto the "AutoPlay" tab. In the pull down box select the type of CD it is, and in the Actions section, make sure "Take no action" is not selected.
Or, select the action, "Prompt me each time to choose an action".
can read cd containing photos. can't read cd from HP containg printer software download.
