    I am having the exact same problem. I don't know what happened to my Acrobat. It has always worked perfectly. Then somehow it was corrupted and I have tried to update it, restore it or do what I can all to no avail.

    I was wondering if either of you have the Quickbook PDF Printer? This has caused the error in the past with Reader 8.

    I am facing the same problem with the fresh installation of Acrobat reader 8.1.3 . I am unable to uninstall the ver 8 or upgrade it to ver 9. Everytime I try to do so, I get the fatal error "The installation package could not be opened, please contact the application vendor". Please help , I am unable to open any pdf file.
    I have a new machine with lots of software are installed in the last few days. therefore I cannot restore it to any previous day.

    thanks in advance and hoping to get a positive from you soon.

    Is anybody who is receiving this error message running CA Antivirus? Reason I ask is I found this article in a different blog:

    "It turns out it was a conflict with CA antivirus and Adobe. It matters what order they are installed .
    To fix I unistalled CA anti-virus> rebooted> Uninstalled Adobe Reader>downloaded Reader 8.0>installed Reader".

    I haven't tried it yet, but was just wondering if there is a common amoungst us all like CA Antivirus?

    Are you using Firefox? I got this error(adobe failed to load core dll) after installing Adobe 9 and believe that was the problem. There are instructions for installing Adobe 9 in Firefox. The link is on the intall Adobe Reader 9 page. I couldn't follow the directions exactly because they are probably for an older or different version of Firefox than I have but basically you have to tell Firefox to allow www.adobe.com to allow add-ons. I uninstalled Adobe, rebooted and followed the directions to allow add-ons and reinstalled. Ta-da! It works now!

    For Acrobat 9 one posible solution is delete AcroRd32.dll.2.config and try to start Acrobat Reader Again.

     

    Bye

    This has become fairly frustrating for me. I read through the other questions with the same problem, there seem to be very many ... and I wonder why adobe products isn't responding. I have many of the same potential items each of us thinks is the "culprit".  I don't know what CA antivirus is, but it does seem that after I loaded stopzilla antivirus recently, I too, have this dll problem.

     

    My pdf loaded and it was actually working today, but when I pulled up the docs I wanted to read, they were garbled/jumbled or in some other format that was indecipherable. Now when I try to load a pdf file, it won't even load, I have the same problem about the" core dll won't load".  I wonder,

     

    So, it's got me thinking why.... and... I recently responded yes to a question adobe asked in an updare or something... or should I say offered, about (can't remember exactly what it was) but it was something like, do you want us(adobe) to maintain internet security for ???, I can't remember what they were tracking or what it exactly asked, but I said yes and I wonder if that security is the problem. Does anyone have clarification for my "garbled/jumbled" speak?!

    I cannot open the program.   Adobe failed to load its Core DLL.  Wondering if it has a compatibility problem with Bit Defender 2011 which I recently installed?   So where is the answer from Adobe's techincal support staff?

    OK I got mine fixed.  here is what i found on the support website under Adobe REader

     

    Windows users

    You can also repair Adobe Reader using Control Panel:

    1. In Windows, choose Start > Control Panel, and then double-click Add or Remove Programs.
    2. In the Add or Remove Programs list, click the Adobe Reader item.
    3. Click Change and follow the instructions to repair the application

      2. In the Add or Remove Programs list, click the Adobe Reader item.
      3. Click Change and follow the instructions to repair the application

     

     

    I followed the instructions and Adobe could open the new Reader afterwards.

    I had the same problem but I just discovered that it only gives me that message and won't open PDF files in Firefox. I can open them and it works fine with Google Chrome. Hope this helps. I tried the repair option and that did  not work. It must be an issue with Firefox.

    in Control Panel and it works for awhile and then it stops.

    All you should have to do is install the latest version of Adobe Acrobat Reader.  Once installed, change the default program to launch when a PDF is opened to the latest one that you installed.  easiest way to do that. right click on a program, go to Open With..., then Choose Default.  a new dialogue box will open, and you can choose which PDF program you want to open with... make sure you choose the latest version.

     

    What i noticed in my scenario was that i could open PDF files, but only after opening adobe reader x, and going to file--> open--> selecting my PDF.

    but when i had items saved elsewhere i wasnt able to open them like say from the desktop or my documents.  gave me that 'Acrobat failed to load it Core DLL' error.  not fun.

    I'm late to the party, but have FINALLY solved this issue.  I'm running Windows Vista on an old desktop I normally only use for printing.  Unable to print .pdf files with this same issues.

     

    Uninstall the latest (lousy) version of Adobe and installed version 9.5.0. 

     

    FIXED.

     

    Abode should have addressed this issue long ago.

    Keeping the thread alive here. I just had the same problem today on a Win XP machine after installing some adobe updates. My current version of Acrobat is 9.5.1 and my Adobe reader is 10.1.3. There were no issues with the reader, just the error message when trying to open Acrobat. I follow the advice of some of the previous posters and did a repair in "Add/Remove Programs". It took close to 10 minutes to finish repairing and required a reboot. After that everything worked perfectly again.

    It worked for me too, BTW in Win7 it is called Programs and Features instead of of Add/Remove Programs. 

     

    Thanks again!!

    I windows 7 and had Adobe 11 downgraded to 10 thinking that might help no. I have changed the program like all have reccomended to no avail has it worked. I have restored my computer to a date when Adobe worked just fine. I  need my reader for school as my textbooks are PDF's. I am in freak out mode and no clue what to do about it. IF all these ideas are not working.

    Go to Bing.com and search for Old Software Downloads and there will be several sites that have really old versions of software, which might be good for at least getting your through your schoolwork!  Good luck!

    MJA741,

     

    I need mine for school it never did it until yesterday too. I am freaking out b/c it is my last week in class and they do not accept late work, plus I am an online student. I have unistalled and reinstalled older versions and still nothing. I hope that Adobe would have a number to call as it would be nice to talk to someone instead of waiting for someone to respond.

    Please don't ask me since mine is now working but I forgot how I fixed it awhile back!  Sorry!

     

    You might ask the school or friends if they have an old version that they had downloaded the install file to their Download folder or such...

    Anyone getting this message, please tell us your antivirus.

    And check the antivirus logs to see if they moved/quarantined/deleted anything.

    I have Trend Micro and I know that it has nothing to do with my Anti-Virus. Already tried it with the AV turned off... Besides, it was working for a year before yesterday and no changes were made

    Antiviruses should be updating daily with new definitions, and false positives are a common thing. So I suspect them as being behind this because after all, what else changed?
