    the acrobat reader that is running cannot be used to view PDF files in a browser

      The subject says it all. I'm unable to open a link to a pdf file.
      I'm using Mozilla on a Win 2000 machine.
      Version 8.1.2 worked fine. I see some people have reverted back to this version. Is that the only fix?
        • 1. Re: the acrobat reader that is running cannot be used to view PDF files in a browser
          Having the same issue here; using Windows XP; IE7 and Adobe Reader v9

          'The Adobe Acrobat/Reader that is running can not be used to view PDF files in a Web Browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again.'

          De-installed and reinstalled but it still continues giving the same error at each online PDF i want to open.

          This is -obviously- a rather no-go stopper for me: whats the use of a pdf reader which cannot read online pdfs ..

            It appears reader v9 is an incomplete program. It will not operate as it's supposed to. Adobe does not offer support for it other than this un-moderated forum. We are left to figure it out ourselves. After reading many threads on this problem and not finding a solution at the home page for adobe, I've gone with the popular consensus and uninstalled v9 and reinstalled v8.1.2, which now displays pdf documents in my browser as it did before.
            Adobe is partnered with MS and is following their lead by only offering paid support. They produce half baked products that don't work and then ignore any requests for help unless you show them the money. They are as arrogant and ignorant as their master.

              The funny thing is I used to have a bad opinion of Reader 4 and 5, using Foxit and special plugin strippers then available. With the last couple of versions of Reader I thought they'd got there act together - they worked fine in IE7, Firefox 3 and so when I saw Acrobat Reader 9 was available I installed it immediately - big mistake.

              I suspect they'll get it fixed sooner or later but in the meantime ... I'm glad I kept a copy of the previous version's installer. (I did notice that with previous version 8 checking for updates available did NOT say anything about version 9)

              Sadder, but wiser ... back to version 8 :-[

              Edit add: just checked ... if you have add-on IE View it appears that PDFs are displayed just find (and quickly) in it!
              I guess maybe I will leave Adobe 9 installed for the time being.

                  M.K.MURTHY,

                  What OS and what version of Acrobat/Reader. Have you tried updating to
                  the latest version of Acrobat/Reader? Sometimes it helps to do what the
                  error message says.

                    Bob..try the solutions in this TechNote:

                    http://kb.adobe.com/selfservice/viewContent.do?externalId=333563

                    If you have uninstalled Reader then you need to go to C://Program files/adobe/....and delete all the leftover folders. Then when you reinstall you will perhaps have better results. You probably have folders left from your previously installed versions as well. (which will give you an opportunity to complain about the shoddy Acrobat uninstall). If all else fail go to your Preferences in Reader and on the left click on Internet...then on the right UNCHECK Display PDF in Browser. This will cause all online pdfs to open in the Reader program instead of the browser. No doubt you will find something lacking in this solution as well. Best of luck!

                        I got the same error message - complete rubbish to have released it without testing this. Anyway, I deleted Reader 9 and reinstalled 8 and updated it, still got the error message, so followed the suggestions here from Gene and deleted the left over Adobe Reader 9 folder in the Programs folder. Works a treat now and opens in the browser - I don't want to have Reader files having to open outside the browser - how messy is that.

                          Go to the Support page of Adobe website and enter "the acrobat reader that is running cannot be used to view PDF files in a browser" or knowledgebase ID "kb405461" in the search box. TechNote on the issue and solutions will be provided.

                          I was able to open the document directly from Acrobat/Reader, bypassing the browser by following Solution 2.

                          Good luck!

                            I am using the Adobe customization tool to make a transform for the .msi file for an automated install. It looks like the registry information referred to in Solution 1 in the above KB is not being written to the registry. There is a different entry in the .msi, but nothing gets generated.

                            When I attempt to add the key via the transform, it fails to add anything. When I add it using a reg add command (or manually), it works.

                            Kind of reminds me how Adobe Reader 8 totally horked up the registry permissions so that Adobe Acrobat Pro 7 would fail to install unless a Microsoft tool was run to reset the permissions. Plainly visible when looking at the .msi using an advanced msi editor.

                            Remember when we could trust these guys? For what they are getting for an Acrobat Pro license, this is inexcusable.

                              Ashley,

                              We have had the same issue you are having. I have also used Adobe's customization tool and made a transform. However after that we had to open that transform in Wise Package Studio (we use it for all MSI packaging) and add the registry keys from Solution one to solve this problem. This worked for us. Procedure is basically to create this key manually on a test PC and make sure that it works. Then export this key from the registry and go to Wise Package Studio, open previously created transform and select HKEY_CLASSES_ROOT and right-click to import .REG file. At this time point to your exported reg file and you will be asked to integrate the registry keys properly by Wise Package studio. Accept that change and save your new transform. This worked for us.

                                I've tracked down one possible solution. YMMV.

                                In the Adobe Customization Wizard 9, on the Installation Options page, there are three choices for "Default viewer for PDF files":
                                *Installer will decide which product will be the default
                                *Make Acrobat the default if both Acrobat and Reader are installed.
                                *Make Reader the default if both Acrobat and Reader are installed.

                                If I leave it as Installer decides (top), it seems fine. If I choose Acrobat (middle), I get the error. I'd been choosing Acrobat under the assumption that someone with Acrobat 9 might elect to install Reader 9. And I do prefer sentences that end with a period. ;)

                                This is on a virtual machine with XPSP2, no Adobe products (other than Flash 10 and customization wizard), .NET 2.0, Windows Installer 3.1, MSIE 6, and a few other products. Neither Reader nor Acrobat prior to install -- clicking on a PDF in MSIE would offer to download the file.

                                    I received the same message, too, after I downloaded and installed Reader v9.0. However, then I opened Reader by itself, separately, and it appeared to "finish" installing. Once it had finished, I had no problem in either Firefox or Chrome.
                                    • 15. Re: the acrobat reader that is running cannot be used to view PDF files in a browser
                                      I was having this problem before coming to this forum. Then taking the advice from here, I first uninstalled my Reader v9.0. Then as Gene suggests (post #6), I deleted the folders under Adobe Reader 9.0. Then I reinstalled v9.0 and before doing anything else, I opened the Reader v9.0 by itself as suggested by Kenneth above (post #14). I accepted the terms and when the Reader seemed to have finished coming up for the first time, I closed it and then opened my Firefox browser. Everything works fine now. Thanks to all.

                                        As regards the Adobe Customization Wizard and problems reported by Denis Hubanic and Richard Finegold in earlier posts, it seems this registry setting
                                        HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe
                                        is being written conditional upon the Property

                                        DEFAULT_VERB = (Read/Open) = Use READER or WRITER to open a PDF.

                                        So if you choose Writer in the Wizard, then the Property DEFAULT_VERB = Open and nothing is written to
                                        HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe

                                        If you choose Reader then DEFAULT_VERB = Read and the registry key is written correctly

                                          I was having this issue as well with Firefox 3.0.6 and AR 9.0.0 on WinXP SP3. I closed Firefox, ran the repair process on AR, opened AR (which didn't prompt for anything), closed AR, then launched Firefox. The problem is gone. Thanks guys!

                                            Thanks for the help! I don't know the first thing about computer programs, but you all made the instructions easy to follow! I uninstalled 9 and installed 8....no more problems opening PDF in browser!!

                                              If you have Acrobat Reader 9 and Acrobat 8 installed on your computer, or previously had Reader 8, you might also have issue with older version of plugin in the Firefox folder.

                                              Thank you to Gene Hutton, who posted link to

                                              http://kb.adobe.com/selfservice/viewContent.do?externalId=333563

                                              This is what helped me (pay attention to the version of dll in the plugins folder):

                                              The Acrobat PDF plug-in (Nppdf32.dll) installs to the following folders:

                                              -- Acrobat: Adobe/Acrobat 8.0/Acrobat/Browser

                                              -- Adobe Reader: Adobe/Acrobat 8.0/Reader/Browser

                                              -- Acrobat and Adobe Reader: Program Files/Mozilla Firefox/plugins

                                              If you select a PDF file after installing the plug-in, the PDF file will download to the browser's Temp folder, and the browser will open Acrobat or Adobe Reader to display the file within the browser window. The Acrobat toolbar at the top of the browser window is an indicator that the PDF plug-in installed correctly.

                                              If a PDF file doesn't display properly, then you may need to manually move the Acrobat PDF plug-in to the browser's plug-ins folder, if the plug-in isn't installed there automatically.

                                                I FOUND A SIMPLE SOLUTION--I'M RUNNING VISTA AND ADOBE READER 9:

                                                Like the rest of you I was getting this error message:
                                                "The Adobe Acrobat/Reader is running can not be used to view PDF files in a web browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again."

                                                Here's the simple solution:
                                                1. Open Adobe 9
                                                2. Select Help on main Toolbar
                                                3. Select "Repair Adobe Reader Installation"

                                                It's working fine for me now.

                                                Hope this saves someone the time that I wasted trying to figure this out.

                                                  I have XP Pro SP3, Internet Explorer 7 and Adobe Reader 9, and have this problem too. Tried to uninstall 9, got message that another installation was in progress, and to finish that installation. I couldn't find a way to fix that. Tried to delete Reader 9 one file at a time. Some couldn't be deleted. Was going to try to go back to Reader 8. Finally made it to the bottom of this thread, and saw Jerry's post above. It worked for me too! Too bad this answer can't be moved to the top.

                                                  Here's the simple solution:
                                                  1. Open Adobe 9
                                                  2. Select Help on main Toolbar
                                                  3. Select "Repair Adobe Reader Installation"

                                                    I have Acrobat reader 8.1 and Adobe pro 9 and was having the same problem.
                                                    Here is what worked for me:
                                                    Go into version 9 and go to the "edit" tab. Go down to "preferences" and click on "internet".
                                                    Un check "display in web browser" and close Adobe 9.

                                                    Now when I open an on line PDF, it opens like it should in Reader 8.

                                                    You may have to go into Reader 8 and do the same as above, except, make sure that "display in web browser" is checked.

                                                      When I try to open a PDf file it requests that I indicate the operating system and language and try though I may, I am unable to open it. What must I do to open it. It is very frustrating to have Adobe Reader and still can't open PDF files.

                                                        I'm running Firefox.  I also have both reader and Acrobat installed.  I had to go to Tools/Options/Applications scroll to Adobe Acrobat Document and set the dropdown to "Use Adobe Reader 9.1 (default)".  It had previously been set to "Always Ask".  That seemed to work.  I also did the same thing in IE (the menus are a bit different), and I could open them in IE, too.  I'd previously made sure all the old files from previous versions were deleted, as suggested by others.  I also set both Reader and Acrobat to not open in browser as suggested by others.  Not particularly intuitive set of steps, but it seems to be working now!

We built a transform based on using Reader as the default .pdf handler, changing only the EULA options and the auto-update.  The package was deployed successfully after we built a workaround to fix the 9.1.2 update bug Adobe has yet to truly address. Currently all the Reader 9.1.2 computers are having this same issue, and the registry entry outlined here and in http://kb2.adobe.com/cps/405/kb405461.html does not appear to make a difference even after reboot. We tried to install the entry both through the transform and manually with no luck.  The only working solution appears to be manually configuring the Reader options to handle PDF files from web browsers separately and not in the browser, but with over 100 computers to update and support this is not really a feasible option.  Is there a way to push the preference change out to multiple computers, or are we just stuck with a lengthy workaround due to Adobe's refusal to fix their own product?

                                                              I was able to fix this by opening Adobe Reader 9 and going to Help > Repair Adobe Reader Installation.  I was surprised this simple trick did it after months of investigation and trial and error.

                                                                    I have found the same issues with some of the PC's on our network. So I will give an example: We are a group of Auto Dealerships, and one of my users was claiming that on a website that they use for work purposes (a General Motors Website) that a particular location that he goes to within the website he clicks on a link to download a PDF file. So he will click on the link, and the PDF file opens up. Then he will close the PDF file, and click on the same link and the web browser will lock up for about 90 seconds. Eventually you will recieve the mysterious message ( A problem has been encountered with Adobe Reader and must close) So you allow Adobe Reader to close and if you go to any other website and open Adobe PDF files within IE 7 all open fine, no problem at all. So I 1st went after IE7 thinking that there was an issue, so I downgraded back to IE6, and still the same issue. So then I upgraded to IE8 and still the same issue. Booted the PC in Safe Mode, and the issue goes away, so now I am wondering what does not load in IE when in Safe Mode. I then in turn upgraded to Adobe Reader 9.3.1, and still the same issue, but not when in Safe Mode. So what fails to load in Safe Mode when opening IE. The Google Toolbar. So I uninstalled the Google Toolbar, and no issue from that point on. So I went and downloaded the Google Toolbar again, and low a behold, the issue crops right back up again. So does anyone have any ideas as to why the Google Toolbar would be causing this issue?

After uninstalling the Google toolbar, the issue went away.
