Setup will now exit."&nbsp;&nbsp;&nbsp;I have two CD/DVD drives on my machine (HP Media Center m7170n), so I took the setup CD out of the DVD burner drive and put it in the other drive - presto, fixed.</P> <P>I had this problem before, and couldn't remember what I did to fix it.&nbsp; Posts on this problem are rare, and none of them document a real fix, only workarounds.&nbsp;&nbsp;Unfortunately this is not a 'fix' either, but figured I'd post it for 'post'erity.</P><img src="http://blogs.technet.com/aggbug.aspx?PostID=1190047" width="1" height="1">Visual Studio 2005 Setup Error
