I suspect it will be in the temp folder someplace. Have you tried doing a file search for "Adobe CS6" or "Deploy," both of which are folder names in the path to my extracted downloads (I did not use the downlaod assistant, however).
If all else fails, you can download again from the direct links here: http://prodesigntools.com/adobe-cs6-direct-download-links.html and then you can control where they get saved. It 's important to read down the page and follow the Very Important Instructions above the links listings or it will not work.
No luck finding it. If anyone else knows, please chime in.
