The installers managed through the Adobe Application Manager are not really able to be stored for later installations. My best recommendation would be to just save the trial download installations for CS6 products, most can be licensed as part of Creative Cloud with the "License This Software" option. The only products this doesn't apply to are Acrobat, Lightroom, Flash Builder and Muse.

Hope that helps,
Thanks for the tip. Being new to ACC, I was concerned when I could find where the installers were DL'd to.
