Reader 9 won't open PDF from web browser

I just installed Reader 9, and now when I click on a link to a PDF on a web page I get this message: "The Adobe Acrobat/Reader that is running cannot be used to view PDF files in a web browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again." Since I AM running version 9, this seems peculiar. Any ideas?

    I would not call tech support on this matter because they will tell you that you have to buy a contract before they will help you.  i just went throug that when i called just a few minutes ago on an update that is always failing.

    I had the same issue.  I closed Acrobat 9 Pro and opened just the reader. I wend to Edit > Preferences > Internet and turned off "Display PDF in browser" and now it works.  I'm using latest IE Explorer and when the PDF opened, I look at what version Reader it was and it is 9.4.0.  I hope this works for everyone who was as frustrated as I was.

    Guys,

    We are having serious issues with Adobe Reader 9.3 where very few users can view PDF files within IE8 (Windows 7 or XP SP3).  I've read all these posts and none of these fixes do help quite saldly.  After 3 weeks of researching, I am ready to jump out the window!

    We actually need for these PDF to be viewed within IE and not via Adobe Reader.

    OS: Windows XP, 7

    Adobe Reader: 9.3

    Please do help if you can.

    Thanks!

    hello,

    following regkey must be set so that the reader can view the PDFs in the browser
    HKEY_CLASSES_ROOT / Software / Adobe / Acrobat / Exe
    The key value must be set on the path to the AcroRd32.exe
    For example: "C: \ Program Files \ Adobe \ Acrobat 9.0 \ Reader \ AcroRd32.exe"
    hope that helps

    I saw a reply here to this thread that they did a complete uninstall of previous verions and then did a new reinstall. I followed that and it is now working fine for me.

    PLEASE NOTE: If you are trying to open PDF files in a browser window on Windows 7 x64, then you must use a 32-bit browser! If you use the 64-bit version of Internet Explorer, then the PDF file will always open in a separate Adobe Reader window.

    Re: Reader 9 won't open PDF from web browser

    The issue above, and below has a wider scope then what I am presenting, and although it relates to Microsoft Windows Registry it's not that difficult, and lets face it Adobe Reader functionality is broke anyway... The thing to keep in mind here is the litmus test: You create a new user on your PC, and try the failing feature via your web browser (Internet Explorer 8, in this case, but not limited to...) and the new account is able to open the PDF file inside the browser window. So if your answer is yes it does work, then your on the right path. Also note that if you have multiple users on the PC, and only one is having the issue, you may choose to use one of the other good working accounts to copy the Registry keys from.

    My Scenario included a New PC, New Adobe Acrobat 9, and Alternately Adobe Reader 9, Existing Domain User Profile (from Windows 2003 Active Directory, Windows XP SP3 Client)

    PDF files won’t display in Internet Explorer 8 using Adobe 9

    When setting up a new pc for an existing user, and using the existing user profile you may need to delete the Registry key HKeyCurrentUser-Software-Adobe for the current user on the new PC, and copy this back in from a local user account on the new PC.

    Caveat; this most likely to occur because of additional updates, and versions of Adobe that were installed on the old pc, that are not on the new clean PC. The original existing user Profile contains registry key entries pointing to software that is not on the new pc.

    Note: Always backup/export a registry key before you delete it.

    To Backup the Registry key First Open the Windows Registry Editor via Start/Run "regedit" Then navigate to the key (HKeyCurrentUser-Software-Adobe) Right Click on it, and choose Export, give it a filename I usually use something similar to the original, with origin addendum like HKCU-Jim-SW-Adobe.

    Now Log out of the bad user account, and Log in to the Good user account.

    Repeat the Export Process, naming the file...HKCU-Good-SW-Adobe

    Once you have Exported the Registry Keys from Both Accounts...

    Log out of the Good Account, Log in to the Bad user account

    To import, you can use Windows Explorer, find where you Exported the good key to,

    (making sure you are now Logged in with the afflicted Account)

    Double Click on the good key, and tell it yes you want to add the information, and OK.

    Now because it is a dynamic registry key, you need to log out, and back in one last time for this to take affect. This is with the (so called) bad account (now fixed!!!).

    I spent hours searching and didn’t find this on the internet, and everything I did find was the standard Un-install, all previous versions… Un-install, re-install the most recent version, set your preferences in Adobe for Open PDF in Brower.

    If you are not able to get Adobe Acrobat Reader to open .pdf files in the browser. Even after you check in prefs to show pdf files in the browser.

    Make this modification for all versions of Adobe Acrobat Reader that show under this key.

    -Note: Deleting the key and all subkeys for any older versions also seems to fix this problem. So if you see this key present,

    HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\7.0\Originals

    delete the 7.0 and all subkeys.

    HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals

    -Right click on Originals and choose NEW DWORD Value and name it bBrowserIntegration, hit enter,

    double click on the new value and make sure the value is 1

    This has been working perfectly for us.

    As a matter of fact we have cases where we have to run older ver of AR and that same process resolves our doc gen issues in our in house apps. If we have to maintain AR8 then we delete the 7.0, 9.0 and 6.0 (we have images that go waaaay back) keys.

    To date I am not aware of any tech that has had to generate the bBrowserIntegration key.

    Thanks.

    I've solved the problem, at least, for me. PDF's opening in my browsers (Chrome and IE8 with Windows 7 64 bit) were all working fine until recently, and I don't know what changed it.

    I found that after I exited that message in a box which said that the adobe reader running couldn't open pdf's in browsers and that I needed version 8 or 9, adobe reader 4.0 popped up with a blank grey window. It was installed on my pc for some reason so I just uninstalled it. I also uninstalled adobe reader 9, deleted the exe and started over. Downloaded a fresh copy of 9.3.3 and it's all fine now.

    I may not have needed to uninstall version 4.0, nor necessarily needed to redownload adobe 9.

    I may have had success just uninstalling 9 and reinstalling it from the exe I already had.

    But it takes no time at all to delete everything, redownload and reinstall. Do any of that and you should be good to go again.

    The fix,

    Try installing Firefox browser on the machine.  Open the website up using this browser instead of Internet Explorer.  You will be able to view your PDF's with the current Reader version installed on your computer. When installing Firefox make sure to uncheck the default setting option, this way Internet Explorer will remain your primary choice. I have included a link to a site that will enable you to download the program.
