Why does adobe reader keep trying to open my XPI files?

Recently when trying to download a .xpi file I accidentally clicked on adobe reader instead of the program I wanted to use to open it, and now it repeatedly tries to use adobe reader to open it no matter what I do, I've looked everywhere and I can't change this. Could you please inform me on how to change what I use to open a file?

You can install such an locally saved extension in Firefox by dragging the file in a Firefox tab or use "Firefox/File > Open File" to install the extension.
There is usually no need to open an xpi file directly.

  • Why does Adobe Reader 9.5.0 open pdf created by Excel, but not with Reader X.

    We have a number of pdf's that open 100% with Adobe Reader 9.5.0, but not with Reader X.
    On Reader X, the message “A Number is out of range” is shown and the image is corrupted.
    The image was created using “File SaveAs PDF” from Excel (Office 2007), with “Standard” optimization.
    For interest, if the same “File SaveAs PDF”  from Excel (Office 2007) is used, but with “Minimum Size” optimization set, then the resulting pdf opens perfectly with both Reader 9 & X.
    Distressing that a new version does not work where previous version did.

    HI
    Sorry, my first time posting and I don’t seem to be able to attach the problem pdf to my posting.
    Example of problem file attached. Opens in 9.5.0 but not X

  • Adobe Reader is trying to open all my files

    I was offered the option to Open Files With and somehow I chose adobe reader.... Now all my shortucts and programs have a .lnk extension and I cannot open them.
    How can I undo and rever to the default?

    Michael, thanks for the link.
    First let me mention that I uninstalled adobe reader and everything went back to normal except - of course - I couldn't open a .pdf file which was not good.
    I reinstalled adobe reader hoping that the new install will come clean but once done I was back with the problem.
    The link you sent me lists several solutions one of which is to perform a registry fix which I wouldn't attempt because - as it mentions - I could end up with more serious issues.
    Another solution it mentions is to set the default program to a web browser, email client... etc.   This is simple to do but could you please explain to me what this will do?  Let's say I set the default program to internet explorer.  Will it stay as the default program forever?  Will it open a word document, or corel draw for example?
    Thanks again,

  • Why does Adobe Flash keep trying to uninstall?

    Sometimes when I go to a random web page (today I was on Macrumors), adobe flash player opens a window
    asking if I want to "proceed with uninstallation". I'm really confused... is this a virus or something? It's happened
    periodically when I go to various different sites, always popping up with the same window and trying to uninstall.
    Is there some solution to this?

    Go here and install Flash regardless if you need it or not.
    http://get.adobe.com/flashplayer/
    If the problem continues, you may have the FlashBlock trojan installed download the free ClamXav and run a scan, keep running one every other day.
    Right now it's new and not everyone has a line on it yet to make a up a definition.
    Apple will of course update the safe downloads, perhaps provide info how to remove it
    What it sounds like is when you visit a web page with Flash, something installed is trying to get you to remove it, like prankware.
    I suspect you could have picked this up at a Mac site like MacRumors...someone with a grudge again our most cherished and loved Abode Flash!
    Where would the wonderful World Wide Web be without it?

  • Why does Adobe Reader use the scroll wheel to zoom in/out now, rather than actually scroll?

    Why does Adobe Reader use the scroll wheel to zoom in/out rather than actually, um, scroll? I can't find anywhere to change this function in Preferences, either.

    I had the same problem on my Windows 8 touch screen laptop.  It was driving me crazy! Every time I tried to scroll a page down, the program would zoom the page!  Made reading an ebook difficult.
    I finally found the solution:
    Under Edit select Preferences - General
    Uncheck "Make Hand Tool Use mouse-wheel zooming".

    Why does Adobe Reader change my icons to pdf?

    For the "why", you'd have to ask Adobe. If you are looking for a solution, this may be helpful:

    I have a user on Adobe Reader X.  whenever they open a .pdf file, the form fields do not auto-fill until you click in the box.  Is there a setting that can be changed to make the form open properly?

    Sounds like the form fields were filled in on a Mac using Mac Preview. This cannot be fixed in Reader only Acrobat. Ask the person who filled in the form to redo their work in Adobe Reader.

  • How do i make adobe reader my default to open any pdf file

    how do i make adobe reader my default to open any pdf file?

    What is your current default?  If Adobe Acrobat (X or XI), you can set it in your preferences.
    If it's another program, reinstalling or repairing Adobe Reader will set it to the default program.

  • Why does Adobe Reader constantly crash on Mac Yosemite?

    I have tried deleting and reinstalling and still Adobe Reader and still cannot open any PDFs.  The document briefly flashes and then an error message says to reopen.  I have not been able to find any solution and cannot access any of my PDF files.

    You have not received any answers to your question yet.
    I moved your question from the Adobe Reader for iOS (for iPads & iPhones) forum to the right forum - the Adobe Reader (desktop) forum.  Because you are using Mac OS X Yosemite and the desktop version of Adobe Reader.
    Hopefully, someone from the Adobe Reader (desktop) forum will assist you shortly.

  • Why does adobe Reader XI ask to download Flashplayer when trying to open an Portfolio.pdf document?

    Hello Everyone
    I have a user that created a portfolio in Adobe X Pro. When they send this out to user and they try to open it with the Adobe Reader XI or Reader X it asks them to download the lates Flashplayer.
    All our systems have the latest flashplayer install.
    Any help would be greatly appreciated.
    Thank You
    Dave

    I just have to add my 2 cents. While I'm sure this change in program has some benefit for Adobe, to me it's horrible for the end user and makes Adobe look bad. In my organization's case, we have about 400 systems, of which only about 40 have the Flash Player Plugin installed. Which means 90% of our systems do not currently have what's needed to open these documents. Now we will need to start rolling out both version of Flash Player. Not a huge deal with Kace, but it's still a potential point of failure and extra headache.
    While IE's usage stake has diminished greatly, they're still a big player. However, in IE you only get to the "plugin" version if you tell it you're looking for a different browser. The regular IE user says "I only use IE, so why would I want the plugin for a browser I didn't install?" If the plugin version is the "full" version, then maybe you should consider having one installer that includes both ActiveX and the plugin.

  • Why does Adobe Reader XI (11.0.4.63) keeps crashing in Win7?

    After a few seconds after opening a PDF document or launching the application, it crashes and provides the error below. I've already uninstallaed and reinstalled the application but the same thing happens.
    I also followed the step in the community discussion http://forums.adobe.com/message/5360426#5360426 but I could not even keep the application running long enough to access the settings and accepting the EULA didn't  worked either.
    Please can someone provide assistance if you have similar issues?

    Update to 11.0.5
    Using Windows Explorer navigate to C:\Program Files (x86)\Adobe\Reader 11.0\Reader, then double-click on Eula.exe and accept the license agreement
    Can you open Adobe Reader by itself?  If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].
    If you cannot open Reader by itself, try to disable Protected Mode in the registry; download, unzip, then run the attached registry script
    It could even be a malware issue; see http://helpx.adobe.com/acrobat/kb/reader-core-dll-error.html
