    Unable to successfully download Production Premium CS5.5

    CKSCBNA Community Member

      Hello

       

      I am using a corporate broadband network and have tried for 3 days and 2 nights to download Production Premium CS5.5 for Mac (the main installer which is 8.8 GB). We purchased 4 licenses, but I'm unable to download the installer.

       

      Friday, I left the Akamai Downloader working all day and left it over the weekend. Although bandwidth consumption data indicated it downloaded the file many times, the result was a DMG file which would not verify and open.

       

      Monday, I downloaded the DMG file as HTTP download, but it would not verify. I ran an Akamai Downloader download again, but it failed after downloading more than 10 GB.

       

      Today (Tuesday), I did one of each, and once again, the DMG file will not verify.

       

      CS5.5 has been around for too long for this to be a corruption issue at esd.adobe.com, yet that seems to be the only reasonable conclusion. All other installers in Production Premium CS5.5, the entire Production Premium CS6 set, and the entire Master Collection CS5.5 set, have downloaded successfully (MC5.5 failed on Akamai & then succeeded on HTTP download).

       

      If I were downloading over a home DSL or cable modem connection, I might understand problems, but this is a fat pipe I'm working with! I'm no stranger to UDP and TCP transfers, so I understand that Akamai may be using UDP for increased speed, and filling in gaps in the file with repeated downloads. If that's the case, why wasn't the weekend sufficient to complete the file? And why doesn't an HTTP download which results in a 100% complete download result in a working file?

       

      Adobe, what other ideas do you have for me?

          Have you worked with your I.T. department to determine if they might have something set up which is interferring with your download?  Perhaps there is a data cap on how much you are able to download under your account?

           

          Besides that you can complete the following steps to disable the checksum function:

           

          1. Go to Applications/Utilities/Disk Utility
          2. Go under the Disk Utility menu and select Preferences
          3. De-select the verify checksum option

           

          If you receive installation errors then the download is truely corrupt.  Otherwise once the install is complete please turn this feature back on.

            Thank you very much, Jeff. Last night, I left it downloading (HTTP) and again, it did not verify upon opening.

             

            Your workaround does work to open the disk image. I won't know until I try installing whether the image is truly defective. Thanks so much for the idea, though.

             

            As all the other modules I downloaded worked fine, I am puzzled that this one file doesn't seem to want to download correctly.

              Your welcome Chris.  This may still be something you may want to be on the look out for.  While researching this issue for other users I found that it is not related to any particular software manufacturer.  If you see this type of error coming up often then it indicates either a problem with the Internet Connection or the Operating System.  I wouldn't recommend taking any additional acton right now regarding this but it is something to look out for in the future.

                I haven't had this issue before, however I've never downloaded software of this size before. All software downloads have been tens of MB. And the only multi-GB downloads I do are between servers locally.

                Our overseas offices often request that I break up files into 1 GB chunks for downloading, and now I understand more acutely why!

                 

                Thanks again,

                Chris
