I want to prevent Adobe from automatically opening PDF files I download from Microsoft Edge.  The suggested solution is to use CTRL+K to open Preferences and then uncheck the box titled  “Always open PDFs downloaded from the web”.  However, the screenshot below shows that this option does not exist for me at all.  Please help. 

In New Acrobat Reader interface, the option Menu → Preferences → Page Display → Always show document page size doesn’t work properly:1. If the option is Checked, the following bug happens:→ the page size and horizontal scroll bar to the bottom doesn’t reach the left side of the screen if Fit to width, Fit height, or Actual size view modes are selected (see screenshot below);→ manually choosing custom view modes (50%, 200%, etc.) eliminates the bug and make the page size and horizontal scroll bar reach the left side of the screen properly.2. If the option is Unchecked, another bug happens that can be reproduced as follows:→ Open a PDF file;→ In “Menu->Preferences->Page Display”, uncheck “Always show document size page”;→ In “Menu->Preferences->Documents”, check “Restore last view settings when reopening document”;→ In the right-side panel, click “Resize the page to fit vertically within the window”;→ Close the PDF file;→ Open the PDF again and see that the static page size a

I have tried several times now to install an update to Acrobat (64-bit) on my Microsoft Surface Pro.  The update keeps failing with the following error" error 1402.could not open key: hkey_local_machine32\software\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation This is odd for a couple of reasons:1) Internet Explorer is no longer installed on the tablet.2) When I look in REGEDIT, there is a "hkey_local_machine", but not "hkey_local_machine32".

For the last month and a half we have had an issue with Adobe reader not opening. Users report that PDF files and Adobe reader aren’t opening. I checked and multiple processes are running in task manager. I’ve ended those tasks and go to reopen Adobe but it does not launch. Two Adobe processes are running in task manager and at 0% or 0.1% CPU and 0MB or 0.1MB and do not change. There are no logs generated in Event Viewer → Windows Logs → Application or System when Adobe is opened or when the processes are ended. We’ve tried repairing and modifying Adobe but that doesn’t work. Uninstalling and reinstalling Adobe, only works for a day or so and then the issue comes back. Tried uninstalling with Revo uninstaller too but the issue still comes back. Same thing with restarting, works for a couple days then we’re back to Adobe not opening. We have users on the latest version - 26.002.21931 Any ideas on how to resolve?

According to the EULA, installing or using Adobe Reader on a server appears to be prohibited.However, Windows Server 2022 is listed in the system requirements.Could anyone please clarify this apparent inconsistency and confirm whether Adobe Reader can be installed and used on Windows Server 2022?Our use case is straightforward: we simply want to open PDF files using Adobe Reader from a server-side application and print them programmatically.We do not intend to provide interactive access to Adobe Reader to multiple users.Could anyone confirm whether this use case is permitted under the EULA and officially supported?Thank you for your clarification.[Moved to Acrobat Reader by a moderator］

Have installed Adobe Reader on my MacBook Pro 2,3 GHz Dual-Core Intel Core i5, Ventura 13.7.4. Trying to add PKCS#11 Modules so I can sign legal document. Options for "Attach module", "Detach module" and "Refresh" are in light gray color and not operative. Tried to fix the problem with support of Certilia in Croatia, but they told me that this is Adobe issue on Mac OS with latest update and quit a lot of users having same issue for apx. last 50 days. Can You help?

I had search index file that covered about 30,000 files. Files were local but also synced to OneDrive. The index worked as expected - fantastic resource. I recently changed to another OneDrive path. Now when I try to create a new search index i seem to get a random sampling of about 5000 files. Everything builds fine - its just 5,000 of the 30,000 though. Path lengths are not signficantly different. I'm using file paths directly on the computer - not in the cloud. Any ideas what the issue could be?

When clicking on the "use a certificate" menu option under tools, all of the options underneath are greyed out and I cannot select any of them to create a box for a digital signature. I'm fairly certain all of the correct certificates are where they're supposed to be on my laptop, not sure if its something I'm missing in the Adobe app itself? I've had no issues signing PDFs with this certificate in the past or with filling out PDFs. I'm just not able to create a signature block??  

Having a hell of a time figuring out which installer to use for a 64 bit adobe reader deployment via intune win32 app. I located a good process at https://www.youtube.com/watch?v=TVAADl2J65Y for the 32 bit version, but I cant find an offline 64 bit installer that will let me extract the MSI from it.  Why is this so absurdly challenging?!

How do I remove the "Create" from the tob tab bar? I keep hitting it when trying to move documents to another screen etc. and I never create pdfs that way. And while I'm here, I HATE the new update. The zoom and page numbers in the bottom right is annoying AF!!!  Plus, having all the tools pop up to the LEFT with TONS of extra space and absolutly random 'emojis' is absurd. *steps off soap box* So any assistance with removing the "Create" from the top tab or any of the other updates, is greatly appreciated. 

The issue is: When I set text style in a comment to superscript, Adobe displays it as subscript in the comments column.So 5superscript2 would save as 5subscript2. When I open the comment, it displays correctly on screen (5superscript2), but when saved it shows as 5subscript2 in the comments column.[Unsurprisingly I cannot format superscripts/subscripts or in this post either, so had to use text to describe them!]  Is this a widespread problem with Adobe Acrobat Reader 2024.004.20243?Will Adobe ever fix it?

Windows 11 machines, the C:\Windows\Installer folder gets dozens of 1gb .msi files every month? They keep downloading to the folder and never disappear. Some machines have filled up over 300gb of these files hitting that folder.  Any idea what might cause it? It's not a folder we can just willy nilly delete stuff from...any ideas?

Hi all-Our office recently installed Acrobat DC and we are becoming more familiar with it as we go... For me, I receive large scanned document files that I have to read, highlight, redact, sometimes edit and comment. I am able to use the highlight tool fairly easily, but is there a way to highlight in a straight line, rather than to have the shake of a hand make my document look unprofessional?  The highlighter gives me a circle for a cursor and it does not hug the text line at all. Any help is appreciated.ThanksFrank

previously no issue. today I have received multiple emails from different senders with pdf attachments. I can't open, preview or save them

I work with medical billing documents regularly, so I often have to review and organize a large number of PDF files.I’m curious how other Acrobat Reader users keep their documents manageable when there are many files to review. Naming files properly and keeping folders organized helps, but I’m always interested in finding simpler ways to work with PDFs.What Acrobat Reader features or habits help you most when dealing with a large number of documents?I’d especially like to hear tips for searching, reviewing, organizing, or sharing PDFs efficiently.

How do I stop my apps from converting files to .25 files? For example, when I save a PDF from Excel using the file name "Estimate, 02.05.25" the .25 in the file name converts the file from a PDF to a .25 file instead. I can't figure out how to stop this from happening or has anyone else experienced this as well?
