Acrobat/Reader 10: Save button not working for PDFs referenced from long URLs

Issue

If you are using Adobe Acrobat/Reader in Firefox/Chrome to view PDF files from long URLs you may notice that  the Save button is not working as expected.  It may be disabled (greyed out), or it may be enabled, but clicking on the button does not bring up the Save dialog to save the PDF to the local file system.

In some organisations the PDF files may be loaded from complex applications which require long URLs to serve parameters with the PDF.  For example:

http://helpx.adobe.com/content/dam/kb/en/837/cpsid_83709/attachments
/Acrobat_Enterprise_Administration.pdf?timestamp=t1115222011102&a=1234567890
123456789012345678901234567890123456789012345678901234567890123456789
&dkmtid=doc&ext=.PDF#FDF=http://server/XML.xfd

The URL above will show the PDF, but the Save button will not work as expected:

Reason

This is an issue with some versions of Adobe Acrobat/Reader 10 in Firefox/Chrome, and will be resolved in a later update for Acrobat/Reader.  The issue occurs when the URL contains more than 259 characters, as Firefox attempts to use this URL as the file-name in the Save dialog.  Such a long URL can exceed a file system limit and therefore the Save dialog does not appear.

Workarounds

  • Use shortened URLs to avoid the issue.
  • Use Acrobat/Reader in Internet Explorer.
  • Use Acrobat/Reader 9 with Firefox/Chrome.

Solution

This issue does not happen with the latest version of Acrobat/Reader 11, and will be fixed in a future release of Acrobat/Reader 10.

Acrobat/Reader: PDF files not displaying in the browser

If you are having problems displaying PDF files in the browser using Adobe Acrobat/Reader in an enterprise environment, there are 3 things to check in your environment.

  1. Check the registry path for Acrobat or Reader
  2. Repair the HKCR\AcroExch.Document registry key
  3. Change the content-type header on the web server

If these suggestions do not help, then you can try the general suggestions outlined in this technote: http://helpx.adobe.com/acrobat/kb/cant-view-pdf-web.html

Disclaimer:  These procedures involve editing the Windows registry.  Adobe doesn’t provide support for editing the registry, which contains critical system and application information. Make sure to back up the registry before editing it, or contact a qualified computer service professional to do it for you. For more information about the registry, see the Windows documentation or contact Microsoft.

1. Check the registry path for Acrobat or Reader

  1. Go to Start > Run.
  2. Type regedit and click OK.
  3. Browse to the key HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe.
  4. Make sure that the (Default) value is set for the path where Acrobat or Reader is installed.
    • The default path for Reader is “C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe”.
    • The default path for Acrobat is “C:\Program Files\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe”.

Note: If Acrobat or Reader isn’t installed in the default path, make sure that the key’s (Default) value points to the actual location.

If the above registry item doesn’t exist on the system, do the following:

  1. Go to Start > Run.
  2. Type regedit and click OK.
  3. Go to Edit > New > Key and create the missing HKEY_CLASSES_ROOT\Software\Adobe\Acrobat\Exe.
  4. Go to Edit > New > String Value and name this key (Default).
  5. Select (Default), and then go to Edit > Modify. Type the default path (listed above) in the “Value data” for your product.
  6. Restart the computer.

2. Repair the HKCR\AcroExch.Document registry key

It is possible that this key is damaged, is pointing to an obsolete version of Acrobat or Reader, or is pointing to a third-party PDF viewer.

  1. Choose Start > Run, type regedit in the Open text field of the Run dialog box, and then click OK.
  2. Back up your current Registry file:
    1. In the Registry Editor dialog box, choose File > Export.
    2. Type a name for the file and choose the location.
    3. For Export Range, choose All.
    4. Click Save.
  3. Navigate to HKEY_CLASSES_ROOT\AcroExch.Document.
  4. Right-click AcroExch.Document and select Delete; make sure that you have the correct key, and click Yes on any prompts.
  5. Right-click AcroExch.Document.7 and select Delete; make sure that you have the correct key, and click Yes on any prompts.
  6. Repair your Acrobat or Reader installation using one of the 2 methods below:
  • Repair using Control Panel (Windows).  Although you can repair your product installation by choosing Help > Repair [product] Installation, the Control Panel method sometimes provides better results. Close Reader or Acrobat.
      1. Click Start > Control Panel.
        • (Windows 7/Vista) Click Programs, and then click Programs and Features.
        • (Windows XP) Double-click Add or Remove Programs.
      2. In the list of programs, select Adobe Reader or Adobe Acrobat.
      3. Click Change and follow the instructions to repair the application.
      4. When the process is complete, click Finish.
  • Repair from within Reader or Acrobat.
    • (Reader) Choose Help > Repair Adobe Reader Installation.
    • (Acrobat) Choose Help > Repair Acrobat Installation.

3. Change the content-type header on the web server

If you’re a webmaster or have administrative rights to a website, configure the web server to send content-type headers of ‘application/pdf’ for PDF files. For instructions, see the documentation that came with the web server, or see article 305153 on the Microsoft website at http://support.microsoft.com/kb/305153.

Acrobat/Reader 10.1.2: Grey blank page displayed when accessing a PDF from a secure site (HTTPS)

Issue

If you are accessing PDF files in the browser from a secure site (i.e. over a HTTPS connection), then you may be presented with a grey blank page, rather than the PDF file. Hitting “Refresh” in the browser will display the PDF file correctly.

Reason

This is a bug in the 10.1.2 version of Acrobat/Reader and has been resolved in the next quarterly release of Acrobat/Reader 10.1.3.  Update to 10.1.3 to resolve this issue, or use the workaround below if you cannot update to 10.1.3 immediately.

Solution

1. Open Acrobat or Reader.

2. Choose Help > Check for Updates.

Reader/Acrobat will install the update automatically.

If you prefer, you can download and install the update yourself. Click the appropriate link below and locate the 10.1.3 update.

Workaround

  1. Log in to your computer as an Administrator.
  2. Click the link to download the AdobeAcrobatReaderPatch10.1.2_cpsid_93026.zip  file.
  3. Unzip the file to extract the executable AdobeAcrobatReaderPatch10.1.2_cpsid_93026.exe.
  4. Close Adobe Acrobat/Adobe Reader if it is running.
  5. Do one of the following to run the AdobeAcrobatReaderPatch10.1.2_cpsid_93026.exe file:
    1. Double-click the AdobeAcrobatReaderPatch10.1.2_cpsid_93026.exe file.
    2. Run the AdobeAcrobatReaderPatch10.1.2_cpsid_93026.exe file in silent mode by specifying the -silent flag on the command line. Open the command prompt ‘As Administrator’ to avoid UAC prompt dialog.
      Example: <path to AdobeAcrobatReaderPatch10.1.2_cpsid_93026.exe> -silent
  6. Once the process is completed, you receive a prompt stating the result of the operation. You can choose to restart the system (if prompted) at that moment or later, but a restart will be needed to ensure that the fix has been applied correctly.
    Note: When run in silent mode, all dialog boxes are suppressed. No success message or error message appear.
  7. A log is created in the temp directory (%temp%) with the name AcroPatchApplication1012.log. (The changes sometimes only take effect after you restart your computer)

Acrobat/Reader: Attach to Email button not working for PDFs referenced from long URLs

Issue

If you are using servlets or scripts to serve your PDF files in the browser, and you then want to use the standard “Attach to Email” button on the Acrobat/Reader toolbar (also available under the File menu) to forward the PDF to another user by email, you may notice that the PDF does not get attached to the email in some situations.

Reason

When you click on the Acrobat/Reader “Attach to Email” button on the toolbar it sends a request to your default email client to compose a new message.  It will also attempt to create the PDF attachment using the file name specified in the URL where the actual PDF is stored.

The URL may be too long to create a PDF file as attachment if it contains very long parameters as follows:

http://localhost:8080/Simple_Servlet/DMShowPDF?command=getdocuments&PDF=path/123_4567890abcdefghijklmnopqrstuvwxyz_0_0.pdf&sig=0123456789abcdefghijklmnopqrstuv&ts=0123456789012&category=new&stage=EDITING%3B%3B%3B1%3B%3B%3B&docid=S0123456789abcdefghijklmnopqrst&ext=.PDF

In this case the filename of the resulting PDF attachment would be:

123_4567890abcdefghijklmnopqrstuvwxyz_0_0.pdf&sig=0123456789abcdefghijklmnopqrstuv&ts=0123456789012&category=new&stage=EDITING%3B%3B%3B1%3B%3B%3B&docid=S0123456789abcdefghijklmnopqrst&ext=.PDF

This can exceed operating system limits, and therefore the attachment does not get created/added to the email message.

Workaround

Simply reducing the length of the URL, particularly the string which will be used for the PDF attachment file name, will allow the PDF attachment to be created.  Even just reducing it by a few characters is sufficient.

Solution

A cleaner solution however, would be to re-structure the URLs so they are shorter, and/or move the PDF parameter to the last parameter position as follows:

http://localhost:8080/Simple_Servlet/DMShowPDF?command=getdocuments&sig=0123456789abcdefghijklmnopqrstuv&ts=0123456789012&category=new&stage=EDITING%3B%3B%3B1%3B%3B%3B&docid=S0123456789abcdefghijklmnopqrst&ext=.PDF&PDF=path/123_4567890abcdefghijklmnopqrstuvwxyz_0_0.pdf

In this case, the attachment file name will be:

123_4567890abcdefghijklmnopqrstuvwxyz_0_0.pdf

Acrobat/Reader: Firefox crash when using multiple Firefox profiles

Issue

 If you are using Firefox profiles to work with Adobe Reader/Acrobat 9 in the browser, you may encounter a browser crash.  This can occur when you have a PDF open in one profile and a normal HTML page in another profile in Firefox. Then you close the Firefox window with the PDF, firefox crashes with:

sw: firefox.exe Application Error, the instruction at "0x0700609c" referenced memory at "0x00000014". 
The memory could not be "read"

Therefore this error will occur very often and will prevent the users from working.  Firefox profiles refers to the functionality when you start Firefox through the command line with "firefox -p -no-remote", this will open a firefox dialog to manage profiles

Solution

 This is a bug in Adobe Reader/Acrobat 9 and is fixed in version 9.3 onwards.

Reader 9: Typewriter tool not available in the More Tools dialog in the browser

Issue

You are using Adobe Reader 9 in the browser and notice that the Typewriter tool is not available in the More Tools dialog, even though it displayed in Reader 8 in the browser.

Solution

In Reader 8, the Typewriter tool displayed in the More Tools list but disappeared after a user selected it if the PDF did not have the appropriate rights. Because this function confused users, Adobe hid the option in Reader 9 in the browser until the PDF was given rights to use the Typewriter tool.

To use the Typewriter tool in Reader 9 on a PDF opened in the browser, enable this right on the PDF using Adobe Acrobat Professional.

To use the Typewriter tool in Reader standalone, enable the commenting right on the PDF using either Acrobat or Reader Extensions server.

For more details about enabling the Typewriter tool, see http://blogs.adobe.com/dmcmahon/?p=822.

After you enable the PDF to use the Typewriter tool with Acrobat, open it in the browser. The Typewriter toolbar automatically opens in the browser window. You also see the Typewriter tool entry in the More Tools dialog, as shown below:

Additional Information

The Typewriter tool is only supported for static PDF documents. It does not work with dynamic documents because it has the same limitations as standard comments in relation to dynamic documents.
