Receiving error when reinstalling Adobe Creative Suite Design Standard CS5.5 for Mac
I just updated my computer and I'm trying to reinstall Adobe Creative Suite Design Standard CS5.5 for Mac that I purchased several years ago. I keep receiving this error when I double click on install.

Does anyone have any suggestions?
I downloaded the Mac/English file from here: Download Adobe Creative Suite 5.5 products which is where the chat suggested I download it from.
Thanks!
