All my PDF default icons have changed to a folder with a 9 square grid in the upper right corner instead of the red Adobe icon in Windows 11 and Adobe is already my default program to open PDF files.  How can I restore the original icon?  I have already tried switching to another default PDF reader and switched back to Adobe but no luck.Please adviseRJBThis is the new unwanted default adobe PDF icon I have 

!--scriptorstartfragment-->We are using free Adobe Acrobat Reader on Windows. Background:- In our customer environment, about half of the PCs have already been updated from 32-bit Reader to 64-bit Reader in the past.- Because of that, we are now considering moving all remaining PCs to 64-bit Reader as well.- Our current plan is to re-enable automatic updates and remove previous registry/GPO-based controls related to 32-bit/64-bit behavior. Issue:- Previously, in some environments, we observed behavior that appeared to guide or prompt users from 32-bit Reader to 64-bit Reader.- However, in our recent test environment, we can no longer reproduce that behavior.- We want to understand whether 32-bit to 64-bit migration for free Acrobat Reader on Windows is still active and how it is supposed to work now. Questions:1. Is 32-bit to 64-bit migration still active for free Acrobat Reader on Windows?2. Is this migration silent by design, or should users see any prompt or UI?3. If automatic up

I opened a PDF file & I noticed a name of the file is displayed incorrectly. This seems like new bug since I wasn’t having any such issue till now. When I switch between the multiple applications & files, this issue creates confusion for me. I don’t know if I am referring to the correct file or not, so I have to double check the content before proceeding further.Anyone else is facing this? & is there any workaround for this bug?I don’t seem to find option to report it. So if there is one, kindly share that here as well.

Adobe  Reader does not validate isomorphic signature files consistently.We have 2 files signed with EUTL trusted CA and LTA enabled with EUTL TSA (Timestamp).They are both valid according to the Esig DSS validation service, but Adobe Reader (latest and earlier versions) flags one as NOT valid and the other as valid.We have made object-level analysis and no structural differences are found.The one regarded as invalid is based on an editable form that was “frozen” to non-editable before signature. This seems significant. The files were both produced using the latest version of Esig DSS code package, release 6.4. - but same error occurs when we sign the form file with older DSS version.  Screenshots of the example files.  

Hi,I am encountering an "Unsupported Algorithm" error when trying to sign documents with a NIST P-384 (EC) certificate via a PKCS#11 module, although RSA signatures work perfectly with the same setup. Since Adobe's official documentation states that Elliptic Curve cryptography is supported, but the signature cannot be created in this case, I would like to ask for your guidance on how to resolve this. Is there a specific configuration or a known compatibility issue in Acrobat Reader regarding hardware-based EC signatures that we should follow?Best Regards,Melis.

I added a password to an Adobe Acrobat document which works to open the document, as intended, but the same password will not allow me to edit or print (to PDF) the document. I only created this one password. So what's going on? Why is Acrobat not accepting the one and only password I created when it uses that password to OPEN the document but refuses the password for EDITING or PRINTING?

I have installed Adobe acrobat reader on my Mac. When no PDF files are open, I see it automatically opens a “welcome” screen, the default page being the Recent tab. This tab contains advertisements which I don’t like so I would like to hide this tab or perhaps the whole default screen When acrobat reader launches. Can I find a setting to do that in the preferences? Architecture: x86_64Processor: IntelBuild: 25.1.20643.0AGM: 7.1.17CoolType: 10.0.7JP2K: 4.0.2.54782

Hello, I am working for an enterprise working with Acrobat native desktop apps rather than browser-based tools. We have conditional access policies in place via Azure Conditional Access. The rules include device-aware granting and blocking, meaning that users must have a compliant device to be able to access the app after successful authentication. Unfortunately, the Acrobat desktop apps do not send any information about the client and thus, the access is refused. It all comes down to the Primary Refresh Token not being transmitted with the authentication request of the app. If the Adobe team used the MSAL library, this would solve this problem. Can you please have a look at this issue?

When I formally request an Adobe Acrobat Reader Distribution License I am met with a rejection notice for: “License Form can not be provided for the public emails.” Unfortunately, I do not currently possess a custom registered business domain. However, I plan to include Adobe Acrobat Reader on my Compact Disc (CD) products to help my customers view media from their CD(s). I plan to serve around 100 customers this year, until the end of 2026. I am respectfully requesting an Adobe Acrobat Reader Distribution License for the purpose(s) described above. Thank you in advance!

PDFs keep automatically opening after I download them. I changed settings in Chrome already. But when I tried to unclick the "Open PDFs automatically in Reader when they are downloaded in Chrome browser" in Adobe, it will not save!! I'm at a loss for what to do. I've uninstalled Adobe and reinstalled it already. 

After the last update to Acrobat I have been having issues opening any pdf files.  I get an error message stating the file is possibly corrupt.  These are a lot of files that I cannot download again or I created.  My system backs up regularly so the backup file states the same thing.All files were find a couple of months ago.  I need to know how to restore a file in Acrobat.

We use desktop PCs with multiple monitors (2 or 3) and Windows 11. Windows has a feature that it tries to remember on which monitor was app running last time it was closed, and when you open it again it will launch on that same monitor. But this feature doesn’t work properly with Adobe Reader, and since monday it’s kinda broken. Let me explainUser1: three monitors side by side, center is main. User opens some pdf that he never opened, it opens on center monitor. He moves the window to left monitor and closes it. He opens again the same pdf and it opens on the left monior. He closes it and opens different pdf that he never opened before. It opens on center monitor. He moves it to right monitor, closes it and openes again. It opens on right monitor. He closes it and opens previous pdf. It opens on left screen. User is annoyed 🙄.User2: two monitors, right one is main, left one is secondary, new Adobe UI. Users opens pdf from Outlook (classic) running on left monitor. Adobe Reader opens o

I have a few users experiencing issues with acrobat and pro. Where if I have a pdf open that is saved to the c drive. I then attempt to open a pdf from outlook it does not open a second tab with that pdf nor does it open a window with that pdf. The only thing I can see is when I have task manager open there is a instance of acrobat opening in the background processes, but no window gets created for me to see. The strange part is if I have acrobat closed then open a pdf from outlook first. I can then open any number of pdf correctly from any drive or from outlook. It only happens when the user opens a pdf from their c drive first. This issue has persisted through reinstalls of acrobat on multiple different devices. Let me know if I can provide any more information about this issue. The devices are all win 11 most recent updates installed. Most recent version of acrobat/ pro depending on the user. This is also happening on my work device although Idon't use acrobat that much 

Hello everyone,for the past few weeks (possibly since the January Windows Update), we have been getting the following error message randomly when opening different PDFs:'The font ArialMT cannot be found or created'.It doesn't matter whether the PDF file is being opened on a network share or locally.Once the user clicks 'OK', the error disappears after reopening the same file.Affected users so far: 50 Windows 11 Pro 24H2 (26100.7623) Adobe Acrobat Reader Version 2025.001.21111 Continous ReleaseAny help would be appreciate Message displayed (german) 

This is not a question, but a suggestion. This product's version numbering scheme is very confusing and should be simplified. Currently, the version number is a code of YYYY.nnn.nnnn, where Y is the year and n is a number. Use case: It's not intuitive to ask someone to download version “YYYY.nnn.nnnn"  

I installed Acrobat Reader on a Windows 11 machine and am getting a view in which all tools are spread across the screen at different locations as shown in the first image below.Also, some tools are floating around. which I want to avoid.  I want to change the view back to old one I am used to as in second image below. How to get the view on the second imave on a Windows 11 machine. 

I use a new DELL laptop with WIN11, and after some dayes, adobe acrobat is opening only as admin and only if enhanced security/protected mode is offFirst, everything worked, but then, I do not know why, it does not react expept as a admin.With processMonitor, I could find no trace of the reader if I try to start it as a standard use,I tried all possible folder  and registry permission issues with ChatGPT, but nothing helped.Alos reinstalling even with the cleaner tool didn't change anything!

I have a number of documents with links to youtube videos. These had worked a few weeks ago, provided we exported the doc to a PDF rather than 'saved as'. Please can you advise how I make these links now work? Thanks....

Not a question, but a suggestion that this forum should be called exactly what the product is designated “Adobe Acrobat Reader”.

I noticed that the ability to delete pages is still a premium feature. That's ridiculous in 2026! Could you reconsider the FREE vs. PRO options? Many people have the Reader app, and basic tasks should be included, not just viewing.Years ago, I also requested a searchable settings menu. Nothing has changed. Sad.
