Acrobat PDF reader for Internet Explorer may be unloading/neoconservative custom plugin

Hello

My question is basically to understand what is happening in this situation, so that I can find out where is the problem and how to solve it.

We used Acrobat 6.0 SDK to develop our custom plugin. This plugin is basically a wrapper for a few basic tools (note, stamp, text) etc... provided by Acrobat 6.0 SDK. We have also developed a PDFViewer.dll to display the PDF document in Internet Explorer. So when the user load the document on our Web site this PDFViewer loaded with custom plugin and allows the user to these tools.

We install this plugin under < Acrobat X > /Plug_ins/ < company name > / MyPlugin.API.

In our website, we give the list of the documents and when the user clicks on a document, it will load the PDFViewer and custom plugin. We are loading Acrobat.exe in advance so that we can load quickly.  Now, the problem occurs when the user open any other PDF in different tab or an instance of Internet explorer. ? How?

Account for a user of internet Explorer connected to our web site, and then they can see we're going to say 10 documents. 1.PDF, 2.pdf, 3.pdf, etc...

Now when the user select document 1.pdf we are loading that PDF in IE within our PDFViewer plugin with custom. (Here I saw that behind the scene Acrobat.exe is responsible in the transformed by using the Task Manager) / if right now if the user opens another instance of Internet Explore or another tab and open a PDF document, it opens PDF in the standard Adobe Reader PDF Viewer for Internet Explorer resides in (C:\Program Files\Common Files\Adobe\Acrobat\ActiveX).

If at this moment, the user goes back to our site and tried to work on 1.pdf our custom plugin works fine, BUT if the user opens another document (say 2.pdf) the card no longer works basically looks like it is not loaded.

This issue only happens if the user opens a document in another instance tab or internet Explorer and opens PDF which led to open Acrobat Activex for internet explore. If the user opens a PDF document alongside Internet explore it does not create any problem because at that time that ActiveX is not loaded.

So my guess is that something happens when the ActiveX for PDF is loaded in Internet Explorer.

I want to know more what is happening and why it's happening. Because of this behavior, the users of our web site cannot use any other web site that opens PDF documents because then they disconnect and reconnect our web site.

Please we need immediate assistance.

I'm open to provide more details with screen capture.

Thank you

Twinkle

So you have Acrobat and Reader is installed on the same computer?

What version of Adobe Acrobat is used?  Which version of Adobe Reader is involved?

You don't mention what/how your PDFViewer.dll called Acrobat?  Can you comment more about it?

  • My computer will not start, getting warning that the iertutil.dll is missing for Internet Explorer

    Anyone know how to fix this problem? I get a warning saying that the iertutil.dll file is missing for internet explore. When I start my computer, all I get is my screensaver with no office. The only way I can continue any part of my computer is to go to alt del to get to the control task manager.

    Do you mean you see a message like this:

    Explorer.EXE - unable to locate component
    This application has failed to start because iertutil.dll was not found. Reinstalling the application may fix this problem.

    That file should never be missed and it takes an extra effort to remove it on purpose because there are one of 3498 files who cares about Protection of file Windows (WFP).

    If explorer.exe is not running, all you will see is your screen background image.

    The file is in this folder (assuming that XP is installed on your C drive):

    c:\Windows\System32

    Since you can get into the Task Manager do the following:

    Since the Task Manager, click file, new task (run...) and then click Browse and navigate to this folder:

    c:\Windows\System32\dllcache

    If you are unable to find or do not see the dllcache folder, because your system is not configured to display hidden files and folders, simply type the path to the folder name in the "Open:" box

    c:\Windows\System32\dllcache

    Make sure the "Files of type" box is set to show all files (or you will not see any), and then click OK to display all files.

    Locate copy the iertutil.dll file backup in the folder c:\windows\system32\dllcache, made a right click and copy and go back up a folder c:\windows\system32, right-click in an empty area and paste the file there.  Answered in the affirmative if invited to replace the existing file.

    If you can't find the file in the dllcache folder (should be), depending on your installation, there may be a copy of the file on your system in this folder:

    c:\windows\ServicePackFiles\i386

    If you find there, copy the file missing from there and paste it where it belongs

    It is possible that some malicious software or your antivirus/antimalware indeterminate quarantined (actually deleted) the right file and the backup copy of which must be in the dllcache folder.

    In this case, you can download a copy of my SkyDrive and use networks disks (on foot) to bring it to the system afflicted on a USB key or a floppy disk.

    You may be able to 'Run' iexplore.exe in the Task Manager to get on the Internet and just download it.

    I downloaded a copy of XP Pro SP3 file you need on my SkyDrive (everyone has a SkyDrive for file sharing).

    You can download it and when you do, place a copy of the file in these two folders (assuming that Windows is installed on your C drive):

    c:\Windows\System32
    c:\Windows\System32\dllcache (this is where XP keeps backups of important files).

    Here is the link to my SkyDrive and you can get the file you need here:

    http://CID-6a7e789cab1d6f39.SkyDrive.live.com/redir.aspx?RESID=6A7E789CAB1D6F39! 311

    When you see the files available for download, you will not see the extension of file (.exe, .dll, .cpl, .sys, etc), but when download you them they will have the right extension.

    When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, it cannot save the file with an extension (for example, .exe, .dll, .cpl, .sys) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

    You can download the file without the extension, and then rename the file to add the appropriate extension.  You do not want to use a file called rundll32 when the name of the file should really be called rundll32.exe (if the downloaded file has no extension, you will need to change the name of the file to add the appropriate extension to make it work.

    You then put the downloaded files in the correct folders on your system.

    That may not solve all your problems, but at least you will be spending this part and we can then fix the rest.

    Since it is all very suspicious to meI would follow with this:

    Download, install, update and do a full scan with these free malware detection programs at:
    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
    They can be uninstalled later if you wish.
    Restart your computer and solve the outstanding issues.

    Boris

    I had problems too with IE9 and it's updates... as you say all the other updates work I don't think that the Windows Update the question... is IE itself... IMHO...

    For days, I was getting the BSOD and it became progressively worse as the days passed... Now, I have all stable and works very well yet.

    If my suggestion for you is what I did... sort the problem at the source the progam in other - IE there is a form of corruption imho.

    First download and save IE9 to your download folder make sure you have the correct version, for example English Vista 64-bit

    Uninstall the current version... you may have to restart... I suggest you only do it anyway... It is cleaner that way. Then reinstall IE. I suggest that you set up with as few add on the as possible and add them at a later date, as and when you need it, preferably one at a time.

    Once you have reinstalled IE and restarted the kickoff of Windows Update If you have not automatically set to run... and I think that it will update the update of security OK.

    Good luck - let me know
