Keep getting message Adobe Reader failed to download core DLL

I have Adobe Reader and I use Widows 7.  I had used the Adobe Reader with no problems, however, just recently, when I tried to open the program, I got the message "because of compatibility problems, Adobe Reader cannot open in protected mode", so I clicked the option to allow it to open without protected mode, and I keep getting the message "Adobe Reader failed to download its core DLL".  How can I fix this?  Thanks

  • Adobe Reader fails to load Core DLL

    I'm at my wits end here.
    For some unknown reason my Win 7 Home Premium 64-bit Dell laptop has started popping up  the following message about Protected Mode.
    If I choose Do Not open, then Reader just closes.
    If I choose Open with PM disabled, I get:
    I have Kaspersky Antivirus already installed and it has scanned my computer several times. Nothing has been found as a result of these scans. I run the full rootkit scans manually several times as well.
    I've rebooted several times.
    I've reinstalled Reader TWICE. I had to use the adobe Reader Cleaner tool because reader will not uninstall any other way.
    I created an Administrator account just to make absolutely sure it would have the correct permissions - but I still get the message above.
    What do I do now?

    I don't know why this is happening to you; over the last few years that method has always worked.
    Two things to try:
    since you cannot even open Reader by itself, try to disable Protected Mode via the registry: download, unzip, then run the registry script from https://files.acrobat.com/a/preview/e2cfe2ae-d1f3-4f3c-ae1d-d4a50fe66f49
    uninstall Reader XI, then download the new Adobe Reader DC from http://get.adobe.com/reader/enterprise/

  • In Adobe Download Assistant I keep getting message saying 'Installation failed to initialize'.

    I have a Dell computer running Windows 8.1 on which I had Photoshop Elements 11 installed without any difficulty. I uninstalled 11 as I have now bought Elements 13 and have downloaded the Download Assistant but it keeps telling me that 'Installation failed to initialize' so I can't install either the new 13 OR re-install my old 11. I have tried re downloading the Download Assistant and restarting my computer with firewall etc disabled but to no avail. I need to use Elements on a regular basis and I am really disappointed that I have just spent £80 on some software which I cannot install. I have very limited computer skills and I am fast running out of hair as it is nearly all pulled out. Please help!

  • HT4623 When trying to install iOS 7.06 on my iPad I keep getting message that update failed. What do I do now?

    I'm trying to update my iPad2 to iOS 7.06. In  Settings it says there is an update. As far as I can tell the download completes although it seems to download slowly. But I always get a message saying installation has failed. Any ideas on what to do next? Thanks.

    I strongly suggest using the instructions provided in the "Update your device using iTunes" section of the HT4623 article you attached above.

    hello, your useragent (the information the browser sends to websites to identify its version) - apparently mistakenly - shows you're on firefox version 4. please refer to this article in order to reset the user-agent settings in firefox: [[Websites say that Firefox is outdated or incompatible even though it's the latest version]]

  • Fatal error - Failed to install core dll Abobe reader 9.2

    I have tried to update to the newest version of Abode reader and when I try to start the program I get a fatal error "failed to install core dll". I downloaded the newest version on another computer and it works fine so I copied the installation folder on to a CD and tried installing it again on the other computer and still get the error.  Does anyone know how to fix this?  I cannot open any PDF's now without the software.

    I am getting messages that I can't download and read .pdf files since I have the wrong Adobe reader. I know about their security disasters of course, but I downloaded the latest version of Adobe Reader from the Adobe web site and I have other ,pdf file readers as well, and for some reason they won't work either. I have 5 computers running top end processors and RAM. By this I mean I have one, this one which I am using that has an AMD Phenom Black 3.2 Quad-core with 8 GBs of Corsair top DDR2 RAM, my other two AMD have either an Athlon II triple core with 4 GBs of DDR2 Corsair RAM, one with the Phenom X4 965 3.4 GHz Quad-core with 8 GBs of their best DDR2 RAM, and two Intels with the i7 920 Processors using the triple channel 1366 socket processors and one with 8 GBs of low latency DDR3 RAM and the other with 4 GBs of the same RAM. I am getting the message on this one, which has a fresh install of XP Pro X64 operating system, as do the other 4 as well. I have run Avast Business Pro Anti-virus on this one, which I am getting the message on with a single result which I deleted, and also both Spybot Search and Destroy, which came back clean as well as Malwarebytes Antimalware, which got a lot of tracing cookies now removed, and SuperAntiSpware which also found a few cookies also now deleted. Can you tell me what I need to do to get these files to show as .pdf files rather than as a clean blank page. One other issue is that I wish to know how to turn off my downloads so they are saved and Mozilla will give me the option of returning them instead of me losing them all together as it does now. Thanks for your assistance. If there is another Adobe reader I should download and install, could you provide me with the link to it? I appreciate your assistance here

    Why can't I open a pdf file on my desktop?  I have Adobe Reader and running OS 10.10.1  I keep getting the same message: "Adobe Reader could not open '8pdk_96_4.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."

    I tried that.
    I saved the file 8pdk_96_4.pdf to my desktop and tried to open it using Adobe Reader but I get the same message: Adobe Reader could not open '8pdk_96_4.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).

  • I can not open or download files/PDF's. I keep getting the "Adobe Acrobat_Reader win binaries" message box. How can this be repaired so I can see PDF's? Thanks!

    I do not much about computers (old school), but sure could use someone's help! I cannot read anything I try to view from a website. I keep getting a Adobe box popping up that says "Adobe Acrobat_Reader win binaries". Every time I click the "Yes" button, it does nothing. Thanks in advance!

    To make a picture, like I did above - go to ACCESSORIES > SNIPPING TOOL.  When you click on snipping tool, the screen will gray out. Click and drag your cursor from one corner of the area you want to "snip" to the other - when you release, you will have a JPEG - save it as any other picture, or even email from the snip you just made.
    THat doesn't advance the PDFs trouble solution, but it's good to know!

    When Creative Cloud updated a few days ago (Win7) it reported I had no installed apps.
    In Lightroom I keep getting messages that a new version is available. Installed it from CC and it installed without error, CC shows I installed it, but it simply fails to run.
    How do I get CC to find apps installed under the previous version?
    And how do I get Lightroom CC to run?
    Peter

    I still don't know how to get CC to find that I have Photoshop CC installed, but running Creative Cloud, going to Preferences and signing out, then signing in again got Lightroom CC to work.
    Since Photoshop CC is still working despite apparently not being installed things are now OK, at least for the moment. But I'm not feeling at all happy with Adobe.
