Adobe Reader plugin forbids displaying PDFs from outside domains

One part of web application is local digital signing using activex component. But I want to display a PDF that gets signed beforehand and after. Since documents can be quite large I would'n really want uploading them and then again downloading for displaying.
Therefore I wanted to embed a PDF using local path (eg. file:///) but Adobe throws "Access denied" error. I tried lowering Reader's security settings to minimum but it didn't help.
Is there any way to embed a PDF with source ouside of the web application domain?

Solved it. Problem seemed to have been a crashed Acrobat process. Just kill all Acrobat tasks in the task manager, reload the link in the browser and the Save button now works.

Adobe Reader X - Disable "Display PDF in Browser" via Registry

I'm trying to configure my organization's Windows workstations so that web-based PDF files open in Adobe Reader rather than in internet browsers. I have been able to configure Adobe Reader 9 installations to open web-based PDF files in Reader rather than internet browsers by using the following registry setting:
Hive
HKEY_CURRENT_USER
Key path
Software\Adobe\Acrobat Reader\9.0\Originals
Value name
bBrowserIntegration
Value type
REG_DWORD
Value data
0x0 (0)
My problem lies with Adobe Reader X: I used the following settings in attempting to prevent Adobe Reader X installations from opening web-based PDFs in internet browsers:
Hive
HKEY_CURRENT_USER
Key path
Software\Adobe\Acrobat Reader\10.0\Originals
Value name
bBrowserIntegration
Value type
REG_DWORD
Value data
0x0 (0)
Hive
HKEY_CURRENT_USER
Key path
Software\Adobe\Acrobat Reader\10.0\Originals
Value name
bAllowByteRangeRequests
Value type
REG_DWORD
Value data
0x0 (0)
Hive
HKEY_CURRENT_USER
Key path
Software\Adobe\Acrobat Reader\10.0\AVGeneral
Value name
bBrowserDisplayInReadMode
Value type
REG_DWORD
Value data
0x0 (0)
I've only had partial success, though. Internet Explorer respects the registry settings and opens web-based PDFs in Reader X. Firefox 14.0.1, though, ignores the registry settings and opens web-based PDFs in Firefox.
Is there a different registry setting I should be using so that Firefox sees "Display PDF in Browser" unchecked and allows web-based PDFs to be opened in Reader X? Is there another method I should be following for deploying this setting to Adobe Reader X clients?

Hi,
We'll, you've educated yourself well. Unfortunately, Acrobat products can't control what browsers do so uniform behavior is not possible. The setting is Adobe's best attempt and forcing some consistency.
The ReadMode setting only controls what happens in the UI after the PDF is open.

Adobe Reader XI not displaying PDF in IE11

Hello, I'm sure there's a small detail/option I'm missing. I have PDFs that I need displayed within IE11 and the browser displays an x where the file should be. I've verified the Internet options under Preferences are correct in Reader.
I've reset the browser, ensured the Adobe PDF add-on is enabled, and completely reinstalled Adobe Reader XI (along with removing folders/reg keys).
None of these have brought about success in displaying the PDF.
Does anyone have any workarounds or something I should check/enable?
Any help is greatly appreciated!
Thanks!

Yes: http://support.microsoft.com/kb/2716529
The "Fix it" however only works for Windows 8 and IE10. If you don't want to make the registry change manually, download, unzip, then run the registry script from https://files.acrobat.com/a/preview/8381e091-a712-4864-854c-3d11afd3a405

Adobe Reader won't display PDF in IE Browser Window

I am using Adobe Reader XI and Internet Explorer v. 11.0.9600.17280.
I have tried uninstalling and re-installing Adobe. I've also checked IE Add-Ins and all Adobe Reader Add-Ins are enabled.
However, you're poorly written software STILL WILL NOT display PDFs in browser any more.
I need help, but since you're software is so horrible, you do not offer typical technical support.
PLEASE HELP!

My company is having the same problem and I was hoping for some kind of final explanation.
The fix of resetting the Internet Explorer settings works for a time, then it later it has the problem again. Our company has a reporting site which needs the documents to open in the browser to allow for drill down(generating another report based on a link in the document), so the reports have to be in the browser not a separate Adobe Reader Window. We have tried other fixes on the Web like the TabProcGrowth=1, but still the problem happens later.
Our users are tired of resetting their Internet Explorer settings every week or more. As this has worked in all previous versions, I would agree the issue probably lies in Internet Explorer or at least partly in Internet Explorer, but we need some way to keep the files opening in the browser rather than a separate Reader window. Any additional thoughts or fixes by anyone would be greatly appreciated.

I have adobe reader but cant open pdfs from emails. Why?

Getting very frustrated as recently cant open pdfs sent to me by emails although I have Adobe reader app on my tablet. Comes up with message Open file failed. Help please
Donut1950

donut1950,
Would you provide more information about your problem so that we can troubleshoot?
What is the version of your Adobe Reader for Android?
What is the version of Android OS?
What is the mail app do you use to read email on Android?
When you try to open an PDF attachment, do you see the dialog "Compete action using" with the Adobe Reader icon? Does the dialog have "Always" and "Just Once"?
Could you tell us the exact error message that you see when you try to open an PDF attachment?
Does the problem happen with ONE particular PDF attachment? Or does it happen with any PDF attachments all the time?

Adobe Reader 9.4.2 - PDFs won't open in IE 8 & IE 9

The recent Adobe Reader 9.4.2 is causing issues with PDFs opening in IE 8 and 9 browsers. Prior to this update our users have had no issues with opening PDFs generated by our website.
Our website generates USPS labels using Siberix ReportWriter software. We have not released any updates for at least a month. Again, before the release of Adobe Reader 9.4.2, there was no issues with our website's PDFs opening in IE browsers.
User System Specs:
Windows XP SP3 and Windows 7 Ultimate
Adobe Reader 9.4.2
Internet Explorer 8 - "File Download" window issue
Internet Explorer 9 - "File Download" window issue
Firefox 3.6.13 - No Issues
Chrome 9.0.597.98 (with Adobe Reader 9.4.2 plugin enabled and Chrome PDF Viewer disabled) - No Issues
The "File Download" window states the following (in addition to a Save and a Cancel button): "The file you are downloading cannot be opened by the default program. It is either corrupt or it has an incorrect file type. As a security precaution, it is recommended that you cancel the download. ..."
We have the following workarounds to address this issue with our customers, but they are not ideal:
Update to Adobe Reader X
Disable "Display PDF in browser" Reader option
Don't update Adobe Reader 9 to 9.4.2
Install other PDF Reading software.
Any solutions to this issue would be appriciated.
Thanks

We are experiencing the same problem, as I mentioned below. I did some research and experimentation, and have a ... workaround. It's not completely satisfactory, but we will go with it until we have a complete solution. Perhaps the following will help others and spur some research in the right direction.
First, a quick review. The problem does not occur with PDFs located on disk; it only occurs with direct streaming of PDF data. Let's also note that the problem does NOT occur with other browsers, e.g. FireFox. So ... technically the problem is not an Adobe Reader problem and we're all on the wrong forum.
My specialty is databases and I'm certainly no expert in this area, but from what I'm able to gather the problem is instead with how IE is recognizing and responding to the MIME type of the streamed data. We're all setting the contenttype to "application/pdf" (or similar) or we wouldn't even be here. But I'm concluding that something - some windows update - has changed the way IE on clients or (in my case) IIS on the server is handling that data stream. If any of you experiencing this issue have servers other than IIS, then the problem is on the client side, I'd say.
Aaaaaanyway, the following articles are old, but helped me:
http://forums.asp.net/p/1036628/1436084.aspx
http://www.techper.net/2008/02/27/4-ways-to-stream-pdf-and-some-tips/
To cut to the chase, the workaround we're going with for now is to add the following to the http response header (this is C#/ASP.NET code):
Response.AppendHeader("content-disposition", "attachment;filename=myfile.pdf");
That causes a popup dialog to appear asking the user to open or save the PDF, something that is familiar to most everyone. If the user asks to open the file, it appears in a browser window just as it did before this problem occurred. Again, this is a temporary solution, but at least the user can see the PDF data in a browser with one extra mouse click.
If an Adobe tech support person or anyone with more experience in this area knows the final solution, I'd LOVE to hear it. Please reply here or in email.
Thanks and good luck all.

Adobe Reader plugin for Firefox - Firefox 17/18 w Reader X/XI unable to view PDF

Our customers are having to use IE, which is not an option at some sites or roll Reader back to 9.4.5 to view our product. This issue started happening on 1/8/13.
No issues opening the PDFs
Originally installed on Win7
IE 8, FF11, Acrobat 9.4.5 – Windows updates turned off since 12/1/12
Installed IE 9, no issues
Installed FF 18.0.1 no issues
Issues opening the PDFs
Installed Reader XI, - kept Acrobat 9.4.5 installed - Unable to open catalogs in FF.

You don't say what it is about your "product" that is different from a regular PDF. I assume from the screenshot you are using LCDRM, but that in and of itself will not stop Reader XI from displaying the content.
Are your Firefox users actually using the Adobe Reader plugin? The latest build of Firefox has its own PDF renderer (which can't load LCDRM-protected files) - you need to specify that you want Reader to be the preferred plugin by changing the Firefox config.

Does Adobe Reader plugin work in Firefox 11 if launched from Gnome?

Sorry to cross post, but I couldn't figure out how to move my post from the "Adobe Reader" forum to the "Adobe Reader for Unix" forum.
If I launch Firefox (version 11) from the command line (Linux shell), then I can open a PDF with the Adobe Reader plugin. But if I launch Firefox from the desktop or panel in Gnome, I get the message "Could not launch Adobe Reader 9.1.0. Please make sure it exists in PATH variable in the environment. If the problem persists, please reinstall the application."
acroread is in the PATH variable - I checked ("which acroread" and "echo $PATH")
We are using acroread 9.3.2. We tried updating to the latest acroread 9.4.something ...? but the SendMail option was missing from Edit->Preferences, so we reverted to 9.3.2.
We are using Debian Linux 5.0.8.
It is very convenient and user-friendly in our library for visitors to be able to view a PDF in the browser (with the plugin) and to be able to just click on the envelope icon from there to send a PDF.
This was working fine until we upgraded to Adobe Reader 9.4. We reverted to 9.3.2, and everything was working fine again. Then our systems people did some things, including updating Mozilla Firefox from version 3.6.13 to version 11. Then the plugin stopped working from the Gnome launch panel. I tried running the old Firefox 3.6.13 from the Gnome launch panel, but the plugin no longer works in it, either.
Has anyone had this problem?
Sometimes running Firefox from the command line gives some errors. I tried various versions of nppdf.so and tried toggling the about:config variable "dom.ipc.plugins.enabled.nppdf.so" but nothing changed.

I have the same or a very similar issue on WIn7 64bit

Adobe Reader 9.3.2 - PDF attachment won't print from right click

Hi all,
Hopefully someone can assist some kind of suggestion, we have just rolled out Adobe Reader 9.3.2 upgrade from v8. When we now try to print a PDF Outlook 2003 attachment from the right click menu, we are prompted with the 'Open With' window. Selecting Adobe Reader 9.3 and press okay opens the document, but it doesn't spool. We can print the document fine from Adobe Reader itself, any ideas?
TIA
Frosty

I have seen the same problem in this forum a couple of times (on Windows Vista and 7 only), but I have never seen a solution for it.
Can you try if Adobe Reader 8.2 does the same? Download it from here http://ardownload.adobe.com/pub/adobe/reader/win/8.x/8.2/enu/AdbeRdr820_en_US.msi
If the same happens with Reader 8.2, then I have no other suggestion than to try an alternate PDF viewer.

Set safari to download pdfs rather than try to use Adobe Reader plugin?

Some websites try to open a pdf file in Safari using the Adobe Reader plugin. I don't have this plugin (and don't want to), and I would like Safari to download the pdf rather than trying to use the Adobe Reader plugin. This option exists in Firefox - is there any way to set Safari to do the same thing?

On my machine, OPTION-clicking a link, downloads it or the PDF that it points to. Alternatively, load the PDF and then OPTION-click on the URL and hit the enter key. Sorry, but that's all I have to offer.

Internet Explorer ONLY passes parameters to Adobe Reader plugin for hosted files, not local

WORKS:
<embed src="http://host.com/test.pdf#page=5"/>
FAILS:
<embed src="test.pdf#page=5"/>
Both code snippets above work when the HTML file is hosted (IIS / Apache). My web-app needs to be able to run from a USB memory stick and work with IE9. The #page param is required for a core feature of the app.
Parameters after the # are passed correctly to the Adobe Reader plugin in Firefox for offline files, eg: file:///C:/test.htm. The documentation only describes hosted examples: http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf
I have tried the <object> route as well with similar results, eg: http://pdfobject.com/
I have burned over 8 hours looking for a solution. I have tried any logical settings in Adobe Reader X, and with the security zones in IE. I am not very familiar with IE security zones, but I suspect it could be related to my issue. I can specify the end-user change any browser or plugin settings as an acceptable solution.

I am developing a hybrid web-application that needs to work both offline (entire website) and in a hosted environment. A key part of the product is displaying PDF's with a dynamic index outside of the PDF. This allows us to use PDF's collected from hundreds of contractors, clients and manufacturers and combine them into one searchable product with a consistent interface. I can specify product requirements including IE browser settings, installed plug-ins etc. I am not trying to cater to a wide audience such as everyone online, but a specific one that is spending $5k-30k for a custom resource.
I expect the limiation is due to a wide cast net regarding security. I tried every setting in IE and essentially fully disabling all security options did not resolve it.
I found a solution, by accessing the ActiveX object directly you can use the exposed classes described here: http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/wwhelp/wwhimpl/common/html/w whelp.htm?context=Acrobat9_HTMLHelp&file=IAC_API_OLE_Objects.103.167.html
Javascript:
var pdfO = document.getElementById('pdfObj');
pdfO.setCurrentPage(pageNumber);
HTML:
<OBJECT id ="pdfObj" data="test.pdf" TYPE="application/pdf">
<a href="test.pdf">Fall-back code</a>
</OBJECT>
This actually works much faster as well, since the plugin doesn't need to be re-drawn in the DOM

Using Maverick, error message: Adobe Reader could not open '***.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).

Receiving error message using current Maverick version: "Adobe Reader could not open '***.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).". Is fix the same as on previous OS versions?

Back up all data before making any changes. Please take each of the following steps until the problem is resolved.
Step 1
If Adobe Reader or Acrobat is installed, and the problem is just that you can't print or save PDF's displayed in Safari, you may be able to do so by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar should appear under the cursor. Click the printer or disk icon.
Step 2
There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.
Step 3
If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Security
and check the box marked
Allow Plug-ins
Then click
Manage Website Settings...
and make any required changes to the security settings for the Adobe PDF plugin.
Step 4
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens by pressing command-V, then press return.
From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.
Step 5
The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others—I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.
Step 6
Do as in Step 4 with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari.

Adobe reader won't open PDF file

I have Adobe Reader 9 and Windows 8 on a Dell computer. When I try to open a PDF file from a website it sends me to my Library on my computer and won't open the file. If I try to open a PDF file from my Desktop, it opens OK. What can I do to fix this?

Do you use Firefox' own PDF viewer, or the Adobe Reader plugin? See http://helpx.adobe.com/acrobat/kb/pdf-browser-plugin-configuration.html

Why can't adobe reader download and display my files?

i downloaded adobe reader and when I try to display something I get an error message:
"Adobe reader is unable to show documents in this browser configuration."
I was able to display these documents with preview..
and I am able to display them with adobe when using my safari browser.
Help!

(for the record)
This is a known issue with the Adobe Reader plugin on Mac OS:
*[https://bugzilla.mozilla.org/show_bug.cgi?id=811085 Bug 811085] - Can't use Adobe Reader for PDF files
Read the above bug for details (please don't comment in the bug report).
To work around this,
#disable the Adobe Reader plugin in the Firefox Tools -> Add-ons -> Plugins list
#choose another action for '''Portable Document Format (PDF)''' content types in the Firefox Preferences -> Applications list, such as "Preview in Firefox" to use the built-in PDF viewer, "Preview" application or the Adobe Reader application itself
