Launching PDF in Firefox yeilds "Could not launch Acrobat.".

I'm running Firefox 2.0.0.6 with Acrobat Reader 8.1.1. When I click on a PDF on a web page I get the error "Could not launch Acrobat.".
The file "nppdf32.dll" is in the Firefox plugins folder.
If I double-click a PDF file on my hard drive, Acrobat launches fine.
Can anyone help?

>>Under Tools->Options->Applications, I have nothing for "Adobe" in my content Type. Any ideas how to get it to populate in there?
Assuming you have acrobat installed, this worked for me:
1. start acrobat (for me this was Acrobat Reader 8 )
2. help -> repair acrobat reader installation
3. stop and restart firefox
now I have entries for pdf and everything works again
[for me, this problem was apparently caused by installing a program that *took the liberty* of installing an ancient version of Acrobat even though I already had 8 installed. After that happened, Firefox refused to open pdf files. I uninstalled the ancient version of acrobat, rebooted etc. etc. to no avail, then found this thread, and looked in Tools->Options->Applications to find nothing for "Adobe"]

  • 8.1.2 "Could not launch" message: race condition at startup

    (apologies for the cross-post; someone suggested that I post this in the Unix forum, so here it is -- I suppose it would have made sense to do this in the first place, I mustn't have been concentrating :-)
    Hi,
    I've recently upgraded our Sun Ray servers to Adobe Reader 8.1.2, and now every so often when browsing to a pdf document, Firefox says
    "Could not launch Adobe Reader 8.1.2. Please make sure it exists in your PATH [...]"
    This seems to be caused by a race condition at startup. The browser plugin runs "/bin/acroread -version", which simply echoes the version number and exits. When it's working, this happens:
    25436: write(1, " 8 . 1 . 2\n", 6) = 6
    25348/1: read(56, " 8 . 1 . 2\n", 20) = 6
    25436: _exit(0)
    25348/1: close(56) = 0
    i.e. the string is written by the script and immediately read by the browser.
    However, occasionally this happens:
    23119: write(1, " 8 . 1 . 2\n", 6) = 6
    23119: _exit(0)
    23008/1: Received signal #18, SIGCLD, in read() [caught]
    23008/1: siginfo: SIGCLD CLD_EXITED pid=23119 status=0x0000
    23008/1: read(58, 0xFFBFB5C0, 20) Err#4 EINTR
    i.e. the read() call is interrupted by the SIGCLD generated by the exiting /bin/acroread process.
    I've inserted a "sleep 5" after line 11 of the /bin/acroread script to try to alleviate this, but I haven't tested it fully.

    Hello Ian,
    Thanks for reporting this. We will try to address this issue in the next release as you have stated a valid race condition issue (though it's difficult to reproduce).

  • Firefox 4 displays "Could not launch Acrobat" error when exiting

    Firefox 4
    Adobe Reader X installed
    OS: Win7 Pro
    Every time I exit Firefox, whether I view a PDF file or not, I get an error message, saying "Could not launch Acrobat."
    I've manually gone Options, Applications and changed them to use Acrobat Reader, but the problem persists.
    The only way I've solved the problem is to reinstall Firefox 3.6.16.
    Any suggestions? I'd like to use Firefox 4, but won't until this issue is resolved.

    Have no solutions to this problem been found? It seems many people have it. I get the error on start up and when shutting down Firefox.

  • Could Not Launch Acrobat

    im on a vista trying to download a pdf but the site gives me an error that says that it 'could not launch acrobat', then after i click the 'OK' button, the middle of the window says 'missing plug-in' so im confused as to what to do can someone help me?

    Are you asking about Acrobat or Reader? Are you saying that since you installed Reader, Acrobat will not open? If this is the case, then you are running into the issue of why Adobe recommends against running both Acrobat and Reader. It can be done with care, but often causes problems and becomes a major problem for uninformed users.
    For Reader questions, you should go to the Reader forum. There has not been an Acrobat Reader product since AA5, and even then it was not Acrobat.

  • Kdcmond could not launch, after security update Nov 09,OS 10.5,Powerbook g4

    Powerbook G4 will not boot past the grey screen with spinning wheel after latest security update from Apple.
    In safe mode: kdcmond could not launch is reported.
    I DO NOT HAVE EASY ACCESS TO INSTALLATION DISKS.
    Please post suggestions that are viable using rm or vi in safe mode.
    It will take the IT department weeks to get around to fixing this so I am hoping for usable responses in the short term.
    Powerbook G4 1GB os 10.5.7 to 8 Grey Screen/crash with exceptions after security update.
    Took corrective actions using Disk Utility then Applejack with no success. Deleted Library/Prefernces/SystemConfiguration files: NetworkInterfaces.plist, com.apple.airport.preferences.plist, and preferences.plist to get them to regenerate. The exception is gone but now, kdcmond could not launch is reported due to no localhost name found.

    No suggestions from anyone so I am giving up and returning the PC to IT. I will leave the thread open in case anyone comes up with any ideas for future reference.

  • After Effects error: Could not launch Adobe Analysis Server (515)   ( 25 :: 101)  *POSSIBLE FIX*

    Hi. Im New to the forums so sorry in advance if i do something incorrect
    Since my Purchase of Adobe CS6, I was not able to use dynamic link, or the plugins that required you to connect to the Adobe Analysis Server (3d Tracker, Warp Stablizer ETC) It would always give me the error
    After Effects error: Could not launch Adobe Analysis Server (515)
    ( 25 :: 101)
    Or if i would use dynamiclink
    The Importer created a generic error
    Through hours and hours searching through the internet, and trying possible fixes, i found possible fixes that might help people with this error.
    *Before attempting any of these fixes, make sure you reinstall CS6 Using the Adobe Cleaner*
    This guide is for Windows OS Only.
    If the error still presists, try these options
    -If your windows account is not a administrator, Run Adobe After Affects CS6 As Administrator
    -Disable your Anti-Virus and your Firewall
    I know you have probably heard this over and over again, but this is mainly the cause of the problem. Some Anti-Viruses even when disabled, go into some sort of one eyed open mode, where it still monitors your computer ever so slightly, so you may want to uninstall the anti-virus. As for the firewall,
    1) Go to your start menu search "Check Firewall Status"
    2)Then to the left of the window, click Turn Windows Firewall on or off
    3)Then tick "Turn of Windows Firewall" on BOTH Home or work network and Public Network.
    -Close and Uninstall filtering and spyware programs such as Netnanny and Premiere Opinion. This might be using the TCP Ports that is needed for After effects, dynamic link and adobe analysis server to communicate
    -Start up Adobe Analysis server Manually. This can be done by going to C:\Program Files\Adobe\Adobe After Effects CS6\Support Files and running Adobe Analysis server.exe as Adminisrator, Then starting Premiere, After effects, etc.
    -If the Adobe Cleaner didnt already, Clean your registry. This can be done with free applications such as CCleaner.
    If none of those options work,  I would suggest a full format and reinstall of windows.
    I hope this would help people with this issue.

    I'm running the latest version. Just installed yesterday.
    You can download and install the latest version (and older versions) of versions 11, 12, and 13 from Adobe right now. That is why I was asking for the exact version number with decimals. Just the other day, someone said they were running the latest version and they weren't aware that CC was even a thing. They were running version 11.0.3 (which isn't even the latest version of CS6 - it's 11.0.4). That's why I always ask.

    I'm on a Mac so I don't have anti-malware, or other security software running.
    That doesn't seem like a good idea. While there can't be anything technically referred to as a "virus" on the Mac OS (due to the underlying structure), there can be (and are) malware variants out there that do attack machines running the Mac OS. As Apple products have grown in popularity, developers have been creating more and more malware aimed at OSX.
    I certainly hope you at least have your firewall running.
    captain_astronaut wrote:
    I tried launching Premiere yesterday and it crashed.
    This points to a much more serious underlying problem. Thousands (if not millions) of people are running Premiere and After Effects on Macs. What sort of error messages did you receive when it crashed?
    Try installing version 12 of AE and the previous version of Premiere as well and see if they run.

  • DW8 "could not launch Macromedia Contribute "

    I am just using DW8 and Contribute 3 in tandem on my new
    Windows Vista machine.
    In Site Definitions, when I hit the 'Administer Site in
    Contribute' button, the re is a flurry of activity and then I get
    the message "Dreamweaver could not launch Macromedia Contribute to
    administer the site. Please check the Contribute installation"
    Any thoughts on this please?
    From memory in Dreamweaver MX a Contribute site can be
    administered from Dreamweaver without Contribute installed. But I
    don't see thta option anymore in DW8. (I originally set up the site
    in DW MX on another machine and I would like to be an administrator
    in DW8 on this machine.)
    Help much appreciated.

    Had the same problem here - "Error - Can not find the
    Macromedia Flash". I was
    using LCARS System47 screensaver from mewho.com. It's an
    excellent and stable
    screensaver, and the best free one I've found with
    dual-monitor support. Adobe
    auto-updated Flash after I'd installed the screensaver, and
    that's when I
    started getting the error. So I thought maybe System47 was
    using Flash. I went
    back to mewho.com, got the latest install, installed over the
    existing, and my
    problem is solved. My kudos to Adobe and mewho.com for
    staying on top of
    things. (Adobe may not have replied to questions in this
    forum, but how could
    they know? It would be impossible for them to test every one
    of the possibly
    millions of real-world scenarios. But their products are
    always top-notch and
    well-supported.)...

  • Could not launch Adobe Stabilization Server Error

    Hey Guys, I'll take you down the road I've been traveling on for the past few hours.
    - Installed CS5.5, everything runs smoothly for the first hour, then I close After Effects,
    - Open it back up again, and receive the "Quicktime in not Installed, some plugin's will not work" So I research that fully, realize it isn't actually a problem and stop thinking about it. I also get an Output Module Error on Startup.
    - I gather some clips together 1920x1080 23.976, normal 60D footage that I was testing to see stabilized, since it worked very well on my 7D footage (But I doubt its the footage that is causing the problem.
    - When I drag, or go into effects and add Warp Stabilization to the clip, I get this error:
    "After Effects error: Could not launch Adobe Stabilization Server. (514) ( 25 :: 101 )"
    - And nothing will happen, can't analyze the footage or the error will pop up again.
    My Mac:
    MacbookPro 17inch
    2.2Ghz Intel i7
    4GB memory
    Running it off of my 1tb 7200rpm external hard drive.
    My Firewall is off (turned it off to test one of the Quicktime error solutions, I've had it both on and off, and both problems stay the same)
    So throw me any bits of info, I know this has been out for exactly a day, but this sucks. I'm just glad that I'm testing it now, and not later
    Thanks guys,
    Zac

    Sorry to hear you're having trouble with the new Warp Stabilizer. We did have a couple reports of this exact problem during beta testing, but were never able to get it to reproduce for us, or even for the beta testers that experienced the problem.
    Some steps/questions:
    0) Take a screenshot of all your running processes using Activity Monitor and Cmd-Shift-4.
    1) What are your _exact_ steps to reproducing the problem (there are many ways to invoke the stabilizer, for example)?
    2) Did you successfully use Warp Stabilizer before on this machine? (I see you already used it on 7D footage successfully)
    3) Does it still happen after you quit & relaunch? (with no other apps running)
    4) Does it still happen after you reboot & relaunch?
    5) If it still happens, try turning Multiprocessing on in the prefs, click OK to dismiss the dialog, then bring it back up and turn Multiprocessing off, and OK again. Then stabilize. Does that help?
    If you get it working, please repeat step 0, then post both pictures comparing before & after.
    Thanks,

  • Could not launch the Adobe stabilization server.

    I am running After Effects Cs6 creative cloud on my MacBook pro with Retina Display, Mid 2012, with 8GB RAM and Mavericks as the OS. I have some shaky video (want to stabilize only 10 seconds of video) and I cannot get Warp Stabilization to work. When I tell it to analyze, it starts and says it's analyzing video, but after 5 minutes it times out and says that it could not launch the Adobe stabilization server. Why is this? I feel like my computer should easily be able to handle this. Thanks!

    Hi garrettborden,
    No other application should be blocking the process. It's usually TCP communication interrupted by either Firewall or other security software.
    Do you mean the "Adobe Analysis Server?" If so, check these things. Mac OS X has a built in Firewall in System Preferences. Can you see if that is set to off?
    If the Firewall is set to "OFF," and you still can't use Warp Stabilizer, others have solved their issues by doing the following:
    Uninstalling and reinstalling After Effects. When uninstalling, please use the Adobe Cleaner Tool to make sure you get a fresh installation: http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.htmlRestart the Mac after doing this.
    Installing After Effects on a new user account, and run that user as an administrator. It sounds like you tried that and it worked for you, but is not ideal.
    If you are still having trouble, please make a screenshot of the Activity Monitor just after you have applied a Warp Stabilizer effect. It would be helpful to see which processes are running, or not.
    Thanks,
    Kevin

    Synfig was made in 2006, so it's not unlikely that it might not work for some people. By 'some people', I mean me. I was just asking if it was something on my side, but if that's all you got, I think it's highly unlikely that it's my fault. I don't even want it anymore, I got Flash Professional. I was just wondering. I could have sworn you used to write more detailed answers before jumping striaght to conclusions. 'Did this happen to you on anything else?' or maybe even 'Why don't you complain to them?' would have been fine.

  • Trying to launch microsoft excel and file could not be found

    installed microsoft office  2011 on a new macbook pro,  word, powerpoint launch but am unable to launch excel
    the error message is  the file could not be accessed

    This is a glitch that can happen sometimes during software update; no license file / agreement is required to install Firefox.
    You can try deleting some files as described at http://kb.mozillazine.org/Software_Update#Software_Update_not_working_properly and then retry the update.
    Or you can just download and install the latest stability update to 3.5.x from here: http://www.mozilla.com/en-US/firefox/all-older.html

  • Firefox 5 will not launch. Error message "Another instance of Firefox is running" is generated every time

    After updating to Firefox 5, on Windows XP machine, Firefox will not launch at all. No matter what I try, I just get the same error message, than Firefox is already running. Even after double checking task Manager, and ensuring that this is not true, as soon as I click to launch it again, the same message pops up. Everything worked well until I updated to version 5.

    Is there any firewall running on your computer that may be blocking internet access?

    If, you change back to Firefox 29 all works without issues.
    How can you get the new version to work Citrix Applciations and Citrix receiver 4.1

    The fix for me was to update to the latest version of Citrix Receiver (4.1.0.56461) and then change the plugin settings for Citrix in the about:addons sections from "ask to activate" to "always activate". All working again for me now :)
