Acrobat Reader is unable to correctly interpret some mountpoint reparse points (junctions). In practical terms: Acrobat Reader is unable to access PDF files from file systems mounted as directories and this is the root cause of the problem.

Junctions are special symbolic links that are used in many scenarios; an important one is when a file system is mounted as a directory rather than a regular drive. Junctions contain 2 paths: a “substitute” path which must be a path in the NTOS namespace (not a Win32 path) and a “print” path, which is to be used for display to the user.

A junction that is used to mount a file system on a directory might have a target like \Device\Volume{GUID}, which might be a file system device. Unfortunately targets such as \Device\Volume{GUID} appear to create problems for Acrobat Reader because it interprets them as the Win32 path C:\Device\Volume{GUID}, which is incorrect.

For more information on this problem please see this GitHub issue:

I am the author of the WinFsp software, which can be used to create file systems and I am happy to answer any questions you may have about this problem.

I have a legal copy of Acrobat Pro X (Creative Suite) that I love (I use it over Creative Cloud supplied by my employer). PROBLEM: I cannot have Reader DC (needed for shared forms sent to me occasionally) installed at the same time as it always acts as default app even though the Windows 10 default app still lists Acrobat Pro. This is as infuriating as when Edge automatically changes this every time there is a Windows update. I already own Finereader 15 that does everything Acrobat does and more and does not require a monthly subscription. You lost a customer when you made your business model change, but stop trying to control my computer.

Acrobat Reader DC was updated to ver.20.012.20041 the other day.

Since then, the following error message appears when printing with the command.

Adobe Acrobat Reader DC has stopped working
The program did not work properly due to a problem.

The program will close and Windows will notify you if there is a solution

Printing is done just by issuing a message.

The command I am using is:
"C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe" /n /p /h "<PDF file path>"

The execution environment is as follows.
OS: Windows 7 Professional sp1 64bit
Processor: Intel(R) Core(TM) i7-6700 CPU @3.40GHz 3.40GHz
RAM: 8.00GB

The following Windows logs are written when an error occurs.

The faulty module name may be "AcroRd32.exe" or "AGM.dll".

In todays world, many browsers now have built-in PDF viewers to help deal with end of browser plugins and the rise of HTML 5 and mobile apps. Can you please consider eliminating browser plugin for Adobe Reader DC and make Adobe Reader a Mac and Windows App store app as quickly as possible to modernize pdf experience and introduce adobe Scan app which uploads scanned document from iPhone directly to mac or windows PC as well.

As many websites are going HTML 5 and browser plugin support is being reduced, we need to see adobe acrobat reader app converted from browser plugin which is obsolete to a app store model on desktops and laptops. I also want to see adobe Acrobat subscription services made available into Windows and Mac App store instead of traditional app installation methods.

I also would like to see Adobe Flash Player and Adobe Air be completely discontinued immediately as flash player and Adobe Air is completely obsolete.

Verion 20.006.20034.39303

When copying from a PDF document the text gets cut off after the SECOND letter 't' when trying to paste.

Steps to reproduce:

1) Open the PDF document attached to this
2) Go to the first page of PDF
3) Highlight the sentence "If the input parameter is a timestamp (without time zone) it applies the offset of the time zone you specify and returns a timestamp with the time zone."
4) Paste into a text editor

Expected Results

All the text is copy/pasted

Observed Results:

Only the following is pasted:

"If the input parameter is a"

Very odd!!

Hi,

after provided more tests were found that (in my case) reason and solution (I saw that behaviour from August 2020 to till now)

Description of workaround and provided steps
- Openned pdf document in Adobe Acrobat Reader DC (still updated version, recently 2020.013.20074),
- In Adobe File/Share file/Outlook message (Office 365 still update, recently version 16.0.13530.20132, 64bit),
- Then is automatically opened Outlook new message,
- message is fulfilled with the data and addresses, then click on send,
- Outlook and Adobe are still opened,

• standard work in both and next application (time to time (hapened not always, olny sporadicaly), don´t know the trigger of issue, but Outlook is seems like freezen (no any reaction to command by mouse or keyboard) - then when you close (standard close of application, not kill the process) Adobe Acrobat Reader DC you can continue with work in Outlook, no further action are required).

Maybe you can find the code bug and reapair it (I will be happy if you can share your feedback).
Thank you.
