Is no longer able to open pdf files in mail, Yosemite 10.10.5 in mail 8.2

Hello

After trying to install the 2016-004 security update 10.10.5 I'm more able to open pdf files in the yosemite in 8.2 mail or on our hard drive.

When you try to install the update, we get the following message:

"Updates available have changed."

• We can install is more up-to-date, even if we downloaded.

• Sent PDF files can only be opened by mail on our iMac

• This has also affected all PDFs, saved the e-mail to the iMac.

• All PDFs in mail over the past four years cannot be open-ended.

• All PDFs over the past four years, saved from mail hard disk cannot be opened by any PDF reader, including preview and Adobe Acrobat.

Any help appreciated

Anthony

Try to install the update mode without failure or another account admin user. If it works, check if you still have the PDF problem. If so, try what is displayed below links Safe Mode.

Safe mode - subject

Safe mode - Yosemite

Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in the system Prefeences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

Isolate a problem by using a different user account

If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

If it works in safe mode, try to run this program when it is started normally, copy and paste the result in a response. The program was created by Etresoft, a regular contributor.  Use please copy and paste the screenshots can be difficult to read. On the screen with the Options, please open Options and tick the boxes in the bottom 2 before the race. Click on the button "Report share" in the toolbar, select "Copy to Clipboard" and then paste into a response. This will show what is running on your computer. No personal information is shown.

  • I can't open PDF files

    I have Adobe Acrobat 9.2 installed. When I receive a PDF file instead of open it using Adobe (as it did in the past) Microsoft Word Viewer takes over and asks me to do a file conversion. Everything goes down hill from there.
    I'm running Vista, I deleted Microsoft Word Viewer under all programs.
    Used to be able to open PDF files without problem.
    If I right click on the file it asks me what program I want to open with; the only option it gives me is OPEN.

    Go to start / Default programs / associate a file or Protocol with a program and highlight .pdf.  Shall be provided to Adobe Reader as the default program, but it probably isn't.  Click on edit, and then see if Adobe Reader is one of the options indicated.  If so, choose it and save your work.  You will now be able to open PDF files.  If Adobe Reader is not one of the options, click Browse and locate the executable file of Adobe Reader (it will be probably somewhere in a subdirectory of the secondary Program Files directory) and select that, like the program by default.  Once again, once done you should be able to once more open the PDF files.  Chances are good that the Microsoft Word Viewer set themselves up as the default for PDF files and now there is noplace to (they have no valid link).  The reason why you have no options to open with, it is that there is probably no configuration of the associations for the PDF files and programs.

    You can also try to uninstall Adobe Reader and then re-install.  That should restore the association and solve the problem.  How to solve the problem, it is up to you.

    I hope this helps.

  • Adobe Pro XI trail is over, but I need to open PDF files

    I was previously able to open all PDFs without going through the trail Pro XI.  I downloaded the trail already when I received a message from Adobe update.  The trail was 30 days, so I accepted because he understood the possibility of converting a PDF to a Word Document.  Now that the track is over, I can't open any PDF files.  I get a message that the path is over and the only option is for me to buy the Pro XI, it does not leave my open PDFs without me by selecting the purchase option.  I want to come back to be able to open PDF files without having to buy the Pro XI and without this coming post on the trail being expired.  I need immediate help because I had to open a PDF days!

    You can use the free Adobe Reader to view and print PDF files.

  • I uninstalled player XI because I wasn't able to open .pdfs longer. Now when I install it, once again, I get message: / downloads/install_reader11_en_mssd_aaa_aih (8) .exe is not a valid Win 32 application.

    I've disabled the viewer PDF Chrome and uninstalled Adobe Reader XI. I have a system of exploitation of 64-bit Windows 7 using the browser Chrome and Adobe worked fine until recently.  How to get the installer to work if I open PDF files?

    It looks like you (or your operating system) try to open your PDF with Microsoft Word instead of Adobe Reader documents.  You must change the file association for .pdf files open with Adobe Reader.

  • I can't open pdf files in firefox, and I tried all the solutions proposed by others. How can I reactivate pdf in firefox?

    I have recently switched to Firefox to Google Chrome, and I find that I can't open all PDFs from the web in some way in Firefox. I can't download them and open them in Adobe Reader and I can't preview them in Firefox, or I can use the plugin from Adobe. I tried to use the solutions posed by users on this site, but none of them have worked. Whenever I have an amendment to the settings to try to resolve this problem, change never allows me to view the pdf file, and the setting reverts to the previous setting after the browser is restarted. I don't like how to display the file, but I need to be be able to see a preview or I need to be able to download it.

    I use an adobe download add-on, 3.0.0.2, and I have disabled. Now, I can actually open pdf files in my browser shows a preview, or download them as I see fit. Thank you!

    But clearly, there is an error with the add-on.

  • Cannot open pdf files with dc, but opens with xi

    Hello. I have Acrobat reader dc under windows 7. I can't open pdf files downloaded from a Web site - the following message is displayed: "Please wait...".

  • Cannot open PDF files in Distiller 8

    Last week I was able to open a PDF with Distiller 8.  Now, when I try to open a PDF file, this is the warning he gives: warning: Distiller is not treated. Newspaper. PDF or. The JDF file extensions

    I do not understand why I was able to open the file one day and not the other.  I was able to select a PDF file and select 'Open with' and Distiller 8 was in the list and the file would open as it would if I had opened in Reader or Acrobat.  I need to open the file in Distiller to make the necessary changes.  You cannot make the same changes to the files in Reader or Acrobat, as you can the Distiller.  Please help me if you can!

    Same answer three years ago, but I will state as simply as possible.

    Acrobat Distiller does not open PDF files in some way, shape, or form. The only purpose of Acrobat Distiller is to convert PostScript to PDF files, nothing more and nothing less.

    If you need to change aspects of a PDF file, including properties, image compression, file size, etc., you open a PDF in Acrobat Pro and use the native PDF that are appropriate.

    FWIW, do not change the extensions of file simply by copying the files to an external drive.

  • Cannot open PDF files

    I have a HP Pavilion desktop pc with card mother at660a and that you just download the latest Mozilla fire fox and now I can't open PDF files when I am still on the web, can I open then, but as soon as I insert in downloads on my drive hard all the that get is a blank page with the exception of the border etc. but no script , by the way this pc has never used Mozilla firefox.
    But when I use internet explore that it's ok, I have Mozilla on my other PC and I have no problem, but they are charged with an earlier version when I try manually open with Adobe reader, he tells me that the file is corrupted hope you can help thank you.

    For some reason, your Firefox is who identified himself as version 9 instead of version 19. If you select help > about Firefox, can you verify that you have version 19.0.2 or click Find updates and get the current version?

    19 of Firefox has an internal PDF Viewer. To switch to a different Viewer, see the following article: How to disable the built-in PDF Viewer and use another Viewer. Note that this does not apply to earlier versions of Firefox.

    Finally, please note that current versions of Adobe Reader 10.1.6 and 11.0.2. For your safety, make sure you have a current version.
