Many of our users cannot open PDF files.  You must select the player as the default PDF Manager once a day.

What was once a rare problem, became a chronic problem, because some changes to group policy by an administrator of AD.  We have disabled all GPs that relate to Acrobat, but we'll still have to connect to workstations users to remember that it is the default manager of PDF in Acrobat Reader (found under Edit > Preferences > General.)

As I mentioned above, this was happening from time to time, and I don't really know why.  We use 9.5, X and XI versions, and each of them have exposed this problem in the past and currently.  If we could find a whole network solution to this question (rather than having to connect to dozens of individual work stations every day), we would be really happy.

Any ideas?

Thank you!

We believe that we have found the answer.  Apparently an admin six years ago had created a batch file named ironically called 'Adobe Fix.bat', who calls a login script to set the following registry key on each computer:

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\SOFTWARE\Adobe\Acrobat\Exe]

"@="\"C:\\Program Files\\Adobe\\Reader 8.0\\Reader\\AcroRd32.exe\"

Since C:\\Program Files\\Adobe\\Reader 8.0\\Reader\\AcroRd32.exe no longer exists on any computer, no PDF files would be the load until you said Acrobat what software to use to open.

Remove this script should solve the problem.

  • my USB won't open it says "you must format the disk hard until you can use it"

    Hello
    I have my brand DANE ELEC 16 GB USB key was the work properly. I took it off wile, he played the song, and since then, I have try to open a dialog box open and said you need to format the hard disk: X before you can use I can't format it because I'll lose my data fields, important documents of songs picters.
    If anyone can help me with it please
    Thank you in advance.

    Because you don't properly stop the disc before removing it, you burned her FAT (File Allocation Table that each player has). Your files are still there, but they can only be read by the 'normal' software... think of a hard drive as a subdivision... formatting a disk (any drive) is like the ranking of all sectors which will be the roads and determine where the accommodation structures (folders) can be placed. When a fat gets grilled, all the rankings and roads disappeared suddenly... but the housing is still there. Recovery software puts the ranking and roads back.

    Is there a software that I used to be called "Rescue" that worked fine on the old disk to FAT32. Costs $60 but it was cheaper than $1000 than for a customer who had sprayed a server hard drive (and replaced their backup before calling me, long story, lesson learned client and I learned the value of disaster planning... but I digress), I was at another time.

    Good luck!! Let us know what you find / use / work... so that you can save we / you... because it will never happen.

  • Why the app for iOS is not a 'back' button? You must select the House then my documents all the time just to open another form of file in this folder. If there is a back button that would save a lot of time for iOS users.

  • Cannot open photoshop after you have downloaded the trial version

    Hello

    Since June I download, uninstall regularly photoshop.

    a each time could not be opened because "of a program error."

    I have Mac Os 10.9.4.

    Thank you for your help

    Hi Julietteneui,

    If you get errors of program, there should be a file named PSErrorLog.txt in the folder Preferences in Photoshop. If this isn't the case, you have a problem with permissions on the Preferences folder.

    To ~ / Library/Preferences. Now open the preferences and settings of Photoshop CC.

    If you still can't find the settings of Photoshop - you have a problem with permissions on the library or preferences folder.

    Kind regards

  • Cannot open documents after you have uninstalled the Office publisher trial version

    Two days ago, I uninstalled a trial of desktop publisher that has happened, that it is the trial period.
    Now when I open a doc ask me to insert the Office xp professional CD but I have Office Home edition factory installed.

    Any ideas?

    Thank you

    It was a trial version, so you couldn't use unlimited number.
    Also if you want to use this application you need to buy this software.

    However, you said that you are an owner of office home edition. Then why you n t install this software and use it instead of Office xp professional.

  • Cannot open PDF files on Web sites, or when it is attached to the email!

    Hello
    My computer is running Vista and I had this problem for the last 2 years! I can only receive the PDF sent by one of the companies I work for. I can't open most PDF files sent by attachment or all the files on Web sites. I have Adobe 9 and Foxit Reader and it does not work with either. I tried to re - install Adobe and still no luck. With Foxit Reader that I can manage to open the PDF files sent from the company I mentioned earlier, but that's all. I would really appreciate some help... Thank you very much! :) x

    Try this: uninstall all the software that you have to display the PDF documents. Then try to open a PDF file. You should receive a message that "Windows cannot open this file". If you get the message that the file is "corrupt" or "not supported" means that you have another program or display of PDF files.
    Once you receive a message that "Windows cannot open this file" download and install the latest version of Adobe Reader (9.3).

  • Is it possible to open old files .swf somewhere in the creative cloud

    I have a 600-page adobe document. How can I copy 2 pages and turn them into a new document? I can highlight pages, export and then combine files into new pdf, but it's very heavy. Acrobat DC, I cannot open 2 files acrobat side by side. In the past, I could take two pages and copy and insert into the document opened adjacent... Thank you

    I'm not what you mean... Start by describing what tools or methods that you use to extract these pages.

    What you write in the first sentence is not true, however. In the dialogue window extract Pages, you can choose whether or not to delete the extracted pages of the original file and extract them as individual pages or not. If you UN-select both options, you will get a single file that contains the pages you have checked out, and they will not be deleted from the original file.
