   Accelerate your creativity by upgrading to the latest versions of your familiar apps.

Enjoy benefits such as cloud storage, file sync across devices, access to Creative Cloud services, and much more.

Important: These instructions are for products downloaded using Akamai Download Manager (Akamai NetSession Interface). These products include software purchased on the 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.

  1. Make sure that the download is complete. If you are unsure whether the download completed successfully, do one the following:
  • (Trial downloads) Check to see if there is a Start Download or Resume Download shortcut on the Desktop. If so, double-click it and wait for the download to complete. Akamai Download Manager removes the shortcut when the download finishes.
  • ( Store downloads) Sign in to your account, navigate to your order, and restart the download. It resumes where it left off. 
  • Navigate to the location where you saved your download. If you see any files ending in ".part" then the download did not finish. ".Part" files are temporary files replaced by .7z, .exe, or .dmg when the download is complete.

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."

  1. Double-click the .exe file (Windows) or the .dmg file (Mac OS) that was downloaded. Follow the onscreen instructions to install the product.
