Libxml2.dll - Entrypoint not found

Everytime I get the libxml2.dll issue fixed, a new iTunes updates seems to bring it back.  Is there anyway to fix this once and for all?  This is a long running issue and I would have thought it would have been sorted out by now.  This should not still be a problem.

tbb.dll (and it's accompagning DLLs) is a DLL that gets normally installed in the system32 directory. As such you should avoid to have it anywhere else on your system. Now it seems tbb gets actually installed by several LabVIEW components and so is already loaded in recent LabVIEW versions when LabVIEW gets started.
Now you might get in a number of troubles here. First if you reference the DLL by path in a Call Library Node Windows will load the DLL as so called SxS (Side by Side) DLL into memory. This is to prevent troubles with different components expecting different versions of the DLL, yet it opens up a big can of worms too. Most DLLs getting installed in system32 do so because they maintain global state and other things internally that gets totally messed up when you load the DLL again from a different location.
Another problem however can be version differences in the DLL. The standard version installed by whatever software makes use of it, may be older than what your own software needs. In that case you have to install the newer version of the library in your system to replace the older version, not put it somewhere else to be loaded in parallel. And keep your fingers crossed, that the library has not introduced incompatible chances between versions, as that would simply make whatever other software has used it before, fail now. Yes it's all DLL hell, but SxS would not be the solution for it either, just a different way of getting roasted in DLL hell.

  • Tbb.dll entrypoint not found

    Hello,
    I have moved a DLL dependant sourcecode with all it´s DLLs but functions from the top DL library fail to load;
    When I select the function click OK, I get an dialog saying that tbb.dll some procedure entrypoint was not found. This is probably caused by loading different dll by labview or the calling dll.
    The top library is using vision.h and there are calls to opencv functions, that probably use some different version of tbb.dll.
    I tried to recompile and rebuild the used DLL in MSVS on the target computer with no problems, but the problem still persists.

    This is a Windows side-by-side issue not a JNI issue. As such it doesn't really
    belong in this forum except as an object lesson to people who create JNI's.
    I had these issues when I moved to Visual Studio 2005 - which, oddly enough,
    was the version of the IDE where SxS support was not only introduced, but
    enforced.
    The fact that you tried to put a SxS folder in the PATH tells me you know
    nothing about how SxS and manifests works. You need to learn about these
    things and then your problems will become blushingly obvious.
    The Binless.dll manifest must be embedded, and it must contain dependency
    entries that specify the SxS requirements, including the version(s) of the
    dependent libraries. Secondly, the specific version of the libraries must be
    installed on the target system.
    My guess is your manifest specifies a CRT version that's not installed on your
    system and that is why the system is complaining. Look for the
    Binless.dll.intermediate.manifest file. It will tell you what your dll expects.
    Here's an example of a dll (debug version) manifest:
    <?xml version='1.0' encoding='UTF-8' standalone='yes'?>
    <assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'>
      <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">

  • I was updating Firefox from version 6 to version 7, after updating I tried to open Firefox and the message I got is this: This application has failed to start because xul.dll was not found. How can I fix this?

    I was updating Firefox to the newest version 7.0.1 from version 6.0.2 I think it was, I clicked the restart Firefox button that always comes up after updating. It started updating and then Firefox never restarted like it was supposed to after it was done updating. I then tried to open Firefox and it told me "This application has failed to start because xul.dll was not found." I did have Firefox crash on maybe about 30 minutes or so earlier which bothered me because I have been using Firefox for years and never had it crash on me before but I didn't think much of it at the time it happened because I was able to go back onto Firefox and finish what I had been working on. A while later I checked for updates and updated. The first time I tried to update it didn't work though so I had to shutdown Firefox and reopen Firefox and start the update a second time. It was after the second time that when I tried to open Firefox I got that message about failing to start because xul.dll can't be found. I filed a crash report when my Firefox crashed. This would have been around 1am-2am in the morning that Firefox first crashed and then wouldn't allow me to open it after updating. I have a DELL laptop running the Windows XP operating system but the laptop is probably at least 6 or 7 years old. The laptop will no longer charge so I always have to have it plugged into an outlet. Both my laptop hard drive and my external hard drive give me messages that I am running out of disk space on my hard drive. I bought this laptop 6 or 7 years ago second hand so it could be even older. In short it's a piece of crap and it gives me all kinds of issues but I currently can't afford a new one, but I have never had any problems with Firefox and I use Firefox more than any other aspect of my laptop so it's really really bothering me. May you please help me fix it?

    Unfortunately I tried that and it didn't work. Thanks for the help though. I tried to uninstall and it said I couldn't because the file is corrupt or something, but I think I finally got it uninstalled and/or deleted or whatever, but now I try to reinstall/download it again from the beginning and I can't. No matter what I do I can not get Firefox working again. No matter how many times I try to redownload it. Any other suggestions?

  • Bridge CS3 (Windows XP) fails to start because Symlib.dll was not found

    Bridge CS3 (Windows XP) fails to start because Symlib.dll was not found? How do I fix this? I've re-installed and the auto updater has run...I even downloaded and ran the patcher application? By the way Bridge CS3 doesn't show up in the CS3 program list in the start menu but it is installed in my program files - I've tried launching it directly from there as well. Bridge CS2 is operating just fine.
    Update: I installed and ran the Adobe Support Advisor, resulting in - Issues: "The module found no solutions to report for the selected log file."
    I tried to package the report and the error read: "The size of the package is too large to be handled with the current configuration! Please contact Adobe Support for additional information."
    I opened a web based report/case number at the Adobe Support Portal about the missing Symlib.dll (including the Adobe Support Advisor error). Their response was: We regret to inform you that complimentary support for your product is not available and/or has expired.

    Did Bridge work before? If so, reset preferences by holding down the Ctrl key when starting Bridge. If successful you will get a Reset Window, choose all 3 options.

  • ITunes wont open,as WebKit.dll was not found?

    iTunes wont open as, error message says "The application has failed to start because WebKit.dll was not found". Does anyone have any suggestions? I've tried to remove iTunes but come up with another error "can't find iTunes.msi"

    It looks like you might have two different problems going on at once. Trying the following one first:
    "The application has failed to start because WebKit.dll was not found".
    Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
    Let's try something relatively simple first. Restart the PC. Now head into your Add or Remove programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
    Does iTunes launch properly now?

  • This application has failed to start because SapNi.dll was not found

    On the advice, good advice, of Melanie and Lars, here is a new thread for my question.
    I'm assisting with a migration of SAPDB, on Windows Server 2003, to MaxDB 7.6.xx on Solaris 10 SPARC.
    I can connect to my SAP DB 7.3.0.35 using Database Manager 7.4.3.23 as superdba. Now I'm trying to use the dbmcli.
    I go to the server and pop open a cmd prompt and try it via dbmcli:
    dbmcli -d sdb -u superdba,<password>
    And I get a Windows dialog box that says
    This application has failed to start because SapNi.dll was not found. Re-installing the application may fix this problem. 
    Hello,
    actually, the SUPERDBA user only has ONE valid password. Although he is able to perform admin tasks and to execute SQL statements, there are not two passwords for this user!
    So if you are able to connect with that user with dbmcli and not with sqlcli or loadercli, there seems to be something wrong with your system/users. Maybe the user called SUPERDBA on your system is not really the SYSDBA but a 'normal' dbm user.
    When you connect with that user with dbmcli, please execute the following commands:
    sql_execute select user from dual
    sql_execute select SYSDBA from dual
    sql_execute select * from users
    Can you also connect with user control with dbmcli? You might want to check the default password (control).
    Regarding the ni.dll problem: If I understand that correctly, you installed Database Studio locally on your PC. Did you also install any othe MaxDB software on that server? When you try to use dbmcli to connect to a remote database, you'll have to specify the -n <hostname> option. Or did you get that dll error on the database server itself?
    Database Studio cannot be used to administer databases of version 7.3. You'll have to use DBMGUI or dbmcli for that.
    Best regards, Melanie
    Hi Melanie, Thanks for the response.
    I cannot use dbmcli at the moment. I get the Windows dialog box saying
    This application has failed to start because SapNi.dll was not found. Re-installing the application may fix this problem.
    I am using dmcli on the Windows 2003 Server with my SAP DB 7.3 installed. Here is the version of dbmcli that I'm using.
    C:\sapdb\SDB\db\bin>dbmcli -V
    OK
    version,os,dbroot,logon,code,swap
    "7.6.06","WIN32","C:\Program Files\sdb\7606",True,ASCII,2
    I'm going to try to do what the error message tells me and uninstall and re-install my DB management applications.
    Thanks,
    Rich

    Hi,
    I just downloaded the Flex 3.3 DK from here:

    Once unzipped I went to run this:
    C:\DATA\My Documents\_jim\flash\open-source\_Software\flex_sdk_3\bin\mxmlc.exe
    When I ran it, I got this error
    This application has failed to start because msvcr71.dll was not found. Re-installing the application may fix this problem
    I searched on Google, and found this:
    http://www.flashdevelop.org/community/viewtopic.php?f=13&t=2932&start=15
    So from there, downloaded "msvcr71.dll", placed here:
    C:\WINDOWS\system32
    And ran the following in the Command prompt: regsvr32 "msvcr71.dll".
    When I did that, I got this error message:
    msvcr71.dll was loaded but the DLLRegisterServer entry point was not found
    The file was not registered
    I saw that the DLL is related to Microsoft Visual Basic Runtime, so I deleted the dll I saved manually, and ran the Microsoft Visual C++ 2008 Redistributable Package (x86) from here:

    Once done, the dll was not placed in the System32 folder.
    I tried the manual install of the DLL again, but on trying to register it again, got the same error message.
    Has anyone else had this problem?
    Seems like I might have hit a brick wall.

  • When I try to open Firefox I receive this message, "Application has failed to start because ssl3.dll was not found." HELP!

    I've been using Firefox for about 3 years. Today, I ran a scan of my computer Webroot Anti Virus and deleted all "risky stuff" they checked. Don't know if this is a coincidence but right after the scan I could not open Firefox. I receive the message, "Application has failed to start because ssl3.dll was not found. Reloading application may remedy this." I reloaded Firefox, the current version, clicked on open and received the same message. I've reloaded Firefox 3 more times with the same results. Now I need HELP.

    See if you can make Webroot restore that file in the Firefox program folder (C:\Program Files\Mozilla Firefox\).<br />
    If not then you need to reinstall Firefox and make sure that Webroot doesn't do that another time.
    You can find the latest Firefox release here:
