Cannot open PDF as cannot connect to DDE Server

We have Adobe Reader X installed on our server and it seems only one person is having this issue...
When she goes to open a PDF file, it states that it cannot open the file as it cannot connect to the DDE server. She also cannot open Adobe Reader X. Any ideas on how to solve this issue?

Can't open file ... error msg "cannot connect to DDE server"?

I can't open my pdf files from Outlook or just open Acrobat. If it does open, it says Acrobat failed to connect to DDE server? I'm using Acrobat Pro 9.3, I think as it updated. I have Win7 with current updates on a new Sony Vaio laptop.
I looked at the other msgs but I am using Norton Anti-Virus not the one mentioned. I am upgraded to Win7 and IE8. All worked ok before switching to new computer and in starting to use Win7 & IE8.
Thanks!
Sherry

I cannot open pdf files from one supplier when using Adobe Reader but I can using another Viewer

I cannot open pdf files from one supplier when using Adobe Reader but I can open it if using Google PDF viewer or another viewer. The Adobe reader gives the error "There was an error opening this document. The file is damaged and could not be repaired" when I try to open the file. The version of Adobe Reader is 10.1.7, however I have tried other versions and they all fail the same way. I have tested on a number of different PC's in different networks and all fail using Adobe Reader but work using alternate viewer. Also the PC's will open a PDF from any other source.

Newer Reader versions are more strict than older versions (and other PDF viewers). If certain minimum requirements are not met, Reader will tell you that the PDF is damaged. This can happen when a document was created with software that does not adhere to PDF standards, or when the file was damaged during a download or email transmission.
You should contact the creator of these PDFs.

I cannot open PDF documents correctly. I get an error on the page that says there is an error on the document. Neither Adobe Acrobat or Reader work.

I cannot open pdf files that are maps correctly . Some of the data layers are missing. I get a warning message that there is an error in the document and I should contact the originator. I have both Adobe Acrobat and the free version of Reader but neither will open them. When I forward them to other clients, they cannot open them either but can open them from the original sender.

Open Tools/Options/Advanced/general/Config. editor, copy mail.server.default.fetch_by_chunks into the search box, double-click the preference to make its value false, OK, restart TB, and see if you still have problems with pdf attachments.
For messages that have already been received in IMAP accounts, you can force a re-download by selecting the Message Source (Ctrl-U), then try to open the attachment.

Help - "Acrobat is being used by another application and cannot open PDF files until the other application is closed."

Hello,
I searched this site and google for this error terminology and come up dry. I support a user who has been for years using Acrobat 5 (yes, I know...) to read files in a client DB program, as well as other PDF files on their PC. In the last week or so, they have started gatting this error "Acrobat is being used by another application and cannot open PDF files until the other application is closed." any time they attempt to open a PDF file attached to an email (via Outlook).
It is my understanding that they cannot upgrade to a newer version of Acrobat because of limitations of their client software, but had not previously had any issues viewing PDF notes from the DB, and PDF attachments in their email.
I have tried uninstalling and re-installing, as well as tried using Adobe Reader 7 & 9 in conjunction with Acrobat to try to get around this issue, but have not been successful.
Any ideas?
Thanks,
Jesse

I don't have an answer to your technical problem. The product I assume is Acrobat that you are talking about (based on the post title), Adobe is the company name. This is a good place to ask questions on Acrobat if folks can figure out what you are talking about. They will ask for the product version number (like AA9.3.3), operating system, and other applications if appropriate. Also, just what you are doing that generates the message.
As for Adobe, you are not likely to get an answer from them here in the user forum. You will be lucky if you can get an answer if you can contact them and not be on hold for more than an hour (sorry, this is why a lot of folks end up in the forum).
So, to help others try to answer your question, what are the products and versions involved? What OS? What are you doing when the message comes up.

I cannot open pdf files in safari. It tells me first character is invalid. I have deleted plug-ins and reinstalled program. HELP

cannot open PDF files in safari. It tells me first character is invalid - I have deleted plug-ins and reinstalled the program.

HI..
If you are using Adobe Reader ...
Try uninstalling the current copy of Adobe Reader first.
Best to use a utility to do this to make sure all the associated files are removed as well > Download AppCleaner for Mac - Uninstall your apps easily. MacUpdate.com
Then reinstall > http://get.adobe.com/reader/
Quit then relaunch Safari to test.

Cannot open PDF files with Reader XI message appears Adobe Reader has stopped working

Cannot open PDF files with Reader XI message appears Adobe Reader has stopped working. A problem has caused the program to stop working

Which Operating system you are using?
Can you open Adobe Reader by itself? If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)] and then try to open the file.

After activating "Click-to-play" plug-ins, I cannot open pdf files.

In the latest release of Firefox, information about how to prevent plug-ins from loading automatically was in the release notes. I activated this in about:config. (Click-to-play).
After that, I cannot open pdf files! When I click on a link all I get is an empty window. Reloading page don't help.
What I can do, is to click on the button next to the awesome bar and set that plug-ins will always load automatically for this page. Then the pdf file loads.
Another work around is to copy the link and paste it in IE.
Is this a bug with "click-to-play"?

Thanks cor-el. I have read the various bug reports and it is indeed the same. Has been known for a while...
Anyway, I find no mention of the work-around: "Click on the button next to the awesome bar and set that plug-ins will always load automatically for this page."
I don't know if there is a place to give that feedback.

Cannot open PDF files on Mac

I cannot open PDFs on my Mac but can open the same files on my PC. When I create a PDF from the computer and when I send it to our office printer as a scan-PDF, I cannot open either. Have downloaded Adobe Acrobat, etc., and still waiting for a response from them. Does anyone have any suggestions?

Don't use Acrobat, use Preview. Preview is already pre-installed on your computer. If you cannot locate it, type Command-Shift (opens Spotlight) and type in Preview and hit return.

Cannot open pdf files with Firefox's built-in pdf viewer

This just started (I think) with Firefox 37.01. This is on Win7-X64. I cannot open pdf files with the Firefox built-in pdf viewer. If I click on the file or try to open it from within Firefox, it brings up a "opening filename.pdf" message. If I select the "Open with" radio button as 'Firefox (default),' it just keeps looping on this process; it never opens. In Tools => Options => Applications, Portable Document Format (PDF) is indicated as 'Preview in Firefox.' I've never had any other PDF viewer installed on this computer. I've tried disabling all plug-ins and extensions, but it still doesn't work. I searched for solutions but haven't found any for this specific issue.
Thanks for the help.

Hello,
Have you tried, to start Firefox in safemode you can do so by following these steps
'''If Firefox is open,''' you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
'''If Firefox is not running,''' you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
;[[Image:SafeMode-Fx35]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Cannot Open PDF in Safari

Can someone please help.
I cannot open PDF files through Safari. I've read some of the other comments on the same/similar issue and I have tried those steps and have been unsuccessful. I still cannot view PDF files through Safari, in fact, the Preview doesn't even open. When it worked the preview icon would pop up in the tool bar at the bottom of my Mac Book, but it no longer does that. Here is what I've tried;
Upgrading my Adobe, even though I know you don't need it for Mac.
Removed Adobe from applications and deleted.
Went to Library and internet plug ins and there is nothing in that folder.
Went to internet preferences and un clicked enable plug ins.
Not quite sure what else to do. Any help would be greatly appreciated. Thank you in advanced.

Hi Roxana ..
Which Mac OS X do you have installed and which version of Safari ??
Upgrading my Adobe, even though I know you don't need it for Mac.
You do if you want to use Adobe Acrobat Reader to view PDF files.
Went to Library and internet plug ins and there is nothing in that folder.
There are two libraries. One is root /Library
The other denotes your Home folder ~/Library (the Tilde character represents your Home folder)
Go to /Library/Internet Plug-Ins
If you see the Adobe PDF browser plugin or just PDF Browser plugin, move that to the Trash. Quit then relaunch Safari. Try a PDF file.

Cannot open pdf with IE/ windows 7.

Dear friends, and those who understand better than I. I have been working on this situation for over a week. I cannot open pdf from the browser. I tried the "patch " as discussed in a different forum, but still only get the link to open in a seperate white blank page. Any ideas? I dont mind going back to an older version other than 10.1.2. I just dont know how to do that either, as I have not had to work this in depth with any software for years.

Thanks for responding to this matter. When I double click the link to open the pdf... a new tab opens with a blank screen. It is white. When I try to refresh, nothing happens. I have also tried to save/download the file, and open it through that way. When asked to save the document "pdf" is not available. Only "all files." However when I try to retrieve it, it says download is not available, as in... it did not download or save.
1. All web browser options are selected. I have already tried to uncheck, one, and all of these boxes. Still the same results.
2. I have tried several URL... All of the documents I have tried to retrieve have been within a secured website, such as salliemae.com (trying to view a 1098 for my student loan), and mycheckfree.com (trying to view bills from ComED and Nicor Gas).
If I open an old pdf on my computer... I can still read that.
Thank you for your time and help. Im so frustrated, and missing deadlines!
