• When I try to open a PDF file with adobe Acrobat reader Windows Media Center automatically appears.

  When I try to open a PDF file with adobe Acrobat reader, windows media center automatically opens. How to prevent this? I just want to open the PDF file with Acrobat reader.

  The solution I think. If you right-click on one of the files and select open the file locations it now combined the file with adobe reader.

  Yes - you simply need to change the associated file (and path) back to Adobe Reader.  (If that's your choice PDF reader.)

  If you did this:

  Press the Windows Logo and R key at the same time to bring up the dialog box RUN.
  Once you have the dialog box up, type in the following command and press OK...

  cmd /k ftype AcroExch.Document

  That he return with? Should be something like:

  AcroExch.Document = "C:\Program files (x 86) \Adobe\Reader 10.0\Reader\AcroRd32.exe" '%1'

• Why does firefox open a non-stop tab string when I try to open a PDF file?

  I don't know if it's a coincidence, but right after that I installed the latest version of Adobe flash player, firefox now opens a string with no end of new tabs, whenever I try to open a PDF file. I have to close the window and start over.

  Help?

  the machine is a HP Elitebook 8540w. Windows 7 64-bit.

  You have configured Firefox to use the Adobe Acrobat plugin? It seems that he may be missing or disabled, because it does not appear in your "more details of the system" (next to your message). You can see the page modules. Either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons

  In the left column, click on Plugins. Then on the right, look for Adobe Acrobat. It may be down on a gray background.

  If you don't have it: Make sure that this isn't your favorite here player:

  "3-bar" menu button (or tools) > Options > Applications

  You can type or paste pdf in the search box at the top of the list after loading to filter.

  If you have it, but it cannot be activated using 'Always enable' or "Ask to activate": You may need to update. I recommend using the help inside your product Adobe (Reader or Acrobat) menu to check the updates.

  Any progress?

• I have Firefox v8. When I try to open a PDF file, all I get is a solid black box.

  When I try to view a PDF file, at the start, I get a transparent box and as soon as I expanded it, it turns into a solid black rectangle. I wonder if there are any add-on which will fix this problem. If I use IE, I have no problem.

  You have two PDF plugins installed for Firefox.

  1. Nitro PDF plugin for Firefox and Netscape
  2. Adobe PDF plugin for Firefox and Netscape '9.4.5.

  Try disabling one that is not used by Firefox and make sure that download Action matches the plugin that you want to use Firefox.

• I have 10 windows and want to drive DC my default PDF reader.  Even if I put it by default, Windows insists on the use of E (new browser) when I try to open a .pdf file.  How can I force Windows to accept the default player?

  The caption explains my problem, that started after the recent update of Windows 10.  Even if the reader asks if I want to make the default value, and even if I click on Yes and then agree that drive to make changes to my computer (probably the registry), the next time I try to open a .pdf file comes from the browser.  In addition, when I open the drive I can't find a way to open a file in it, which leaves me stuck with the browser rather than drive for all the .pdf files.  What can I do?

  Hi robertb98559829,

  If in the case where it does not drive as default value when the application of the parameters of the application, then we need to change the default OS property values.

  Please, try the following:

  Close the player or any other application using the PDF

  Go to control panel > default programs > associate a type of file or Protocol with a program

  Since scrolling list file Type down to the type of PDF file.

  Click on it to select it.

  Click the Change program button at the top right

  On the next dialog box, select Adobe Acrobat Reader and click OK

  Then close

  

  Now, try to open a PDF by double clicking on it.

  I would like to know if it works.

  Acrobat Reader or Adobe Reader? Personally, I wouldn't use Adobe at all, but try this. Skip #1 if it is already on the HARD drive.

  1. download and save the attachment to the office.
  2. right click on the saved file.
  3. Select: Open with on the shortcut menu.
  4. click on: choose [default] program.
  5. Select: PDF reader program.
  6. check: always use the selected program to open this type of file.
  7. click on OK.
