MAC Photoshop Help?

I recently purchased Photoshop Elements 11 Student and Teacher Edition, and was able to install the Premier version, but unable to install the Photoshop Elements 11 version because I was asked to close out of ElementsAutoAnalyzer, PhotoShopServer, and DynamicLinkManager.  However, when I searched my Mac for these programs so that I could close out of them, they didn't exist!  I'm not sure how to proceed; can you please send me some instructions, or a link to what to do in this scenario? 

The message I get when I am prevented from installing is as follows (I also receive this message when I try to UNinstall the software, so uninstalling is not an option):

Exit Code: 24
