Important: These instructions are for products downloaded using Akamai Download Manager (Akamai NetSession Interface). These products include software purchased on the Adobe.com Store and some trial software, including Acrobat X Pro and Creative Suite 5.5.
If the installer doesn’t start automatically when your download completes, you can start it manually.
Tip: If you can't remember or don't know where you saved your downloads, see Find downloaded files. On Mac OS, there is one .dmg file. On Windows, there is an .exe file and possibly a .7z file.
Important: Some Windows product downloads include two files: an .exe file and a .7z file. To install the software, it's necessary that both files are downloaded and located in the same folder. Otherwise, an error can appear when you start the installer. Errors include "Windows cannot open this file" and "The file archive part of Adobe [product name] is missing."
