Thank you again for your response. We're not communicating well.
I am downloading from Adobe.com, Creative Cloud login, Adobe Exchange, Creative Cloud Extensions.
When you select a file to download from this site, it does not use the browser download feature. My browser, Internet Explorer 11 is set to ask for a download location by default.
For some reason, when downloading from Adobe.com, it does not use the download manager in the browser. If you click download, it tells you that you have "acquired" the extension, and you can see the extension in both Extension Manager CC 2014 and the "Manage My Add-Ons" page in your Adobe Creative Cloud profile.
The question is where is Adobe.com Add-ons putting the Extension files on my computer when it says I "acquired" the extension?
