Unable to install reader/view PDF files

Hi all,
Here's another wierd one... suddenly, I cannot download or view PDF files in Safari. I have attempted to download acrobat reader for a re-install, but neither safari nor firefox will download the complete file. Adobe says the file is 21 megs, but when downloaded (takes 3 seconds!!) file size shows 409 Kb everytime I try it. When I click the .dmg I get a message that says "unable to open file... unsupported file type" or similar statement. Any idea what might be happening here? I'm running 10.4.8 and everything used to work fine, although I hated Acrobat because it took 30 seconds to load!!!
Thanks for your input.

Correction... downloaded Reader file is actually a folder named "DownloadReader.pkg" and double-clicking on it causes the message "File could not be opened because the specified format is not supported"

  • I can not view pdf. files on the web.

    I have downloaded the latest Adobe reader.
    I can open and view existing pdf files on my desktop.
    I can not however view any pdf files from web sites.

    Yes, it was working.
    Last week I cleaned up my hard drive using an app. called OmniDiskSweeper.
    I deleted what I thought was an extra copy of Adobe Reader 9.
    Today, I tried to open an pdf file on a website and just got a dark page.
    I tried several different websites with the same result.
    I was able to open existing pdf files located on my desktop.
    I then downloaded and reinstalled both Adobe Reader 9 and Adobe Reader 10.1.3 .
    I am still unable to open and view pdf files on web sites.

  • Unable to open .pdf in Firefox 3.6.8 with Adobe Reader 9.3.3 installed. Error message is "The Acrobat/Reader that is running can not be used to view PDF files in a web browser."

    I am unable to open a PDF file in Firefox 3.6.8. Adobe Acrobat Reader 9.3.3 is installed. I get the error message "The Adobe Acrobat/Reader that is running can not be used to view PDF files in a web browser."

    You can get that error if there is still an old Adobe Reader plugin in the plugins folder in the Firefox program folder.

  • Since I have Yosemite on my iMac I can't view PDF files in Safari anymore.  It keeps telling me to upgrade my Adobe Reader, but it is the latest version.  Please help?  I don't have this problem on my Macbook that does not have Yosemite installed.

    Since I have Yosemite on my iMac I can't view PDF files in Safari anymore.  It keeps telling me to upgrade my Adobe Reader, but it is the latest version.  Please help?  I don't have this problem on my Macbook that does not have Yosemite installed.

    Back up all data before making any changes. Please take each of the following steps until the problem is resolved.
    Step 1
    If Adobe Reader or Acrobat is installed, and the problem is just that you can't print or save PDF's displayed in Safari, you may be able to do so by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar should appear under the cursor. Click the printer or disk icon.
    Step 2
    There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.
    Step 3
    If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select
              Safari ▹ Preferences... ▹ Security
    and check the box marked
              Allow Plug-ins
    Then click
              Manage Website Settings...
    and make any required changes to the security settings for the Adobe PDF plugin.
    Step 4
    Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
    /Library/Internet Plug-ins
    In the Finder, select
              Go ▹ Go to Folder
    from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens by pressing command-V, then press return.
    From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.
    Step 5
    The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others—I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.
    Step 6
    Do as in Step 4 with this line:
    ~/Library/Internet Plug-ins
    If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari.

  • Using Adobe 11 reader, now comes up with an error, once file is opened. 'Invalid plugin detected, Adobe reader will quit. Closes the program so cannot view PDF files. Running windows 7. I have uninstalled and re-installed Adobe still the same. HELP

    Sounds like something has been added into the Reader folder. I would recommend uninstalling, running http://labs.adobe.com/downloads/acrobatcleaner.html, removing any left over parts of the Reader folder (this might have been the problem), reboot, and reinstall. Hopefully that solves the problem. For future question about Reader, you should consider asking in the Reader forum, this is not it.

  • Reader 9.2 - "can not be used to view PDF files in a web browser"

    Hello,
    I recently deployed Adobe 9.2 within our organization. I used the Adobe Customization Wizard 9 to transform the install set, and selected the "Display PDF in Browser" option as default.
    When opening a PDF linked from a web URL, we get the message: "The Adobe Acrobat/Reader that is running can not be used to view PDF files in a Web Browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again." This occurs under IE8 and IE6, in both Windows XP SP2 and Windows 7.
    If I launch Adobe Reader and unselect "Display PDF in Browser" in preferences, PDFs open normally.

    I think I have discovered the answer to my own question!
    I have disabled Adobe Reader plug-in, and can now see PDFs in Chrome.
    (Steps: Chrome Menu, Settings option, Click Advanced Settings link, then Content Settings button, then select Disable Individual Plug-Ins, and a list of plug-ins is offered to enable or disable).
    I then get a different result depending on whether or not Chrome PDF viewer is enabled - with it enabled I see the PDF document in Chrome, or with it disabled then the option is offered to download it, but either way I can get it it via Chrome without having to run Internet explorer in another browser window.

  • The acrobat reader that is running cannot be used to view PDF files in a browser

    The subject says it all. I'm unable to open a link to a pdf file.
    I'm using Mozilla on a Win 2000 machine.
    Version 8.1.2 worked fine. I see some people have reverted back to this version. Is that the only fix?

    "The Adobe Acrobat/Reader is running can not be used to view PDF files in a web browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again."
    Here's the simple solution:
    1. Open Adobe 9
    2. Select Help on main Toolbar
    3. Select "Repair Adobe Reader Installation"
    Yes, but make sure that all previous versions of Acrobat and Reader have been removed from your computer.
    I had on Vista Acrobat Reader 5 and 9 because sometimes was problem with printouts in duplex on Acrobat Reader version 7,8 and 9.
    You can have more then one version of adobe reader on your computer.
    I had to uninstall this Acrobat Reader 5 and select Repair Adobe Reader Installation on Adobe Reader 9.3.3 version.
    Success.

    You can see the installed plugins on the about:plugins page.

    You can set the pref plugin.expose_full_path to true on the about:config page to see the full path of plugins on the about:plugins page.
    It is best not to leave that pref set to true as it exposes that full path to web servers, so reset that pref to false after you are done with the about:plugins page.
    You can open about:plugins and about:config via the location bar, like you open a website (about: is a special protocol to access some build-in pages).
    If you get a warning when opening the about:config page then you can confirm that you want to continue.

  • Unable to view pdf files sourced from websites

    Hi
    I have previously had no trouble viewing pdf files from various websites, however am now unable to.  It appears to be loading and then just comes up with a blank screen.
    I am able to view pdf files which have been emailed without problem.
    I have removed Acrobat Reader & reloaded but this has not helped.
    I am able to view pdfs on our laptop & ipad and the settings appear to be the same.
    Does anyone know what I can do to resolve this problem?
    Thanks!

    For Safari, you need to remove the adobe pdf plugins which Adobe apparently screwed up.  You need to remove:
    /Library/Internet Plug-Ins/AdobePDFViewer.plugin
    /Library/Internet Plug-Ins/AdobePDFViewerNPAPI.plugin
    I think you can "get away with" removing just the second one.  But both for sure should allow you to open pdf's in a browser (all browsers).
    If you are not using Safari the above will work for other browsers too, although in FireFox, you could just disable the use of those plugins from within Firefox (Tools menu --> AddOns --> Plugins).

  • Unable to view PDF files in Infoview

    I am unable to view pdf files in InfoView (Business Objects Edge Series XI 3.0)
    When I select the pdf file from Infoview, I receive the message 'Do you want to save this file' which only allows me to save the document to a location on my computer.
    Other users can view the file in Infoview, so it probably relates to a setting on my computer.
    Any ideas?
    Thanks

    I've had a little look on Adobe's knowledge base; try this to check whether the issue is related with opening PDF in your browser in general:
    "Determine if the web browser can open the PDF file from your local hard drive rather than from the web:
    In the web browser, choose File > Open (or Open File).
    Choose All Files from the Files Of Type pop-up menu (Windows)
    Click Browse
    Select the PDF file you saved in step 1 of task 5, and then click Open to open the PDF file. If Acrobat or Adobe Reader displays the file, but won't display it on the web, the web server has a problem serving the PDF file. Contact the webmaster of the site from which you downloaded the PDF file."
    If so, try the troubleshooting steps mentioned here:

  • Unable to view pdf files in IE 11.

    Unable to view PDF files in IE 11, Winows 7. Works fine in Google Chrome on same pc. Everything is up todate.

    See the solution at http://support.microsoft.com/kb/2716529
    However, that Fix-it won't work on Windows 7; you will need to make the registry change manually.  Download, unzip, then run the attached registry script to change that registry value.

  • Unable view PDF files that I download

    I am unable to view PDF file in Adobe Reader.  I have a pop-up that states "Before viewing PDF documents in this browser you must launch Adobe Reader and accept the End User License Agreement, then Quit and relaunch the browser".  I have no idea where to accept the agreement, because it hasn't asked me to, and I have updated it.  Any suggestions??

    Do exactly what the message says: open the Adobe Reader application (not in the browser!), then accept the EULA.
