As of today 10/02/2025, after doing a "quick print" from my Outlook email, the adobe app stays open and on my screen after printing. I do quick print many times a day from my email and this is so annoying and a hassle. I've checked for an update and there are none right now, must be a bug. Please fix this! Thank you

Any solutions?

!--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.  

Bonjour à toutes et tous,Je cherche une solution à mon problème:Je suis développeur et je crée des formulaires en PDF.Le formulaire fonctionne très bien avec le “ADOBE ACROBAT” professionnel.L’utilisateur peut enregistrer son travail à n’importe quel moment.Par contre, avec le ADOBE READER (gratuit), il n’est pas possible d’enregistrer le formulaire avec des données.Sauf si “Reader Extended” est activé.Si je le fait, le problème s’inverse. Il n’est plus possible (pour ceux qui utilisent la version professionnelle) de sauvegarder leurs fichiers !Quelqu’un aurait il une idée pour résoudre mon problème ?Merci d’avance de votre aideBonne journéeAndré

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!

Hello, we tried to generate a digital signature with PKCS#11:Adobe Acrobat Reader DC version 2021.001.20145Default signing format: PKCS#7 - DetachedPKCS#11 key stored on smart card (QSCD):CKA_KEY_TYPE: CKK_ECCKA_EC_PARAMS: { 1 2 840 10045 3 1 7 }ECDSA elliptic curve P256 with digest algorithm SHA256Windows 10, macOS CatalinaWe successfully loaded the PKCS#11 module. We started the signature process, added the PIN and after we tried to save the document we received the following error message:"Error encountered while signing: unsupported algorithm."The last function is called by Acrobat is the C_GetAttributeValue with CKA_KEY_TYPE: CKK_EC. There is further communication between Acrobat and PKCS#11 module.According to the Acrobat DC Digital Signatures guide, the above-mentioned algorithm is supported:https://www.adobe.com/devnet-docs/acrobatetk/tools/DigSigDC/standards.htmlOn the other hand, with Minidriver, we can generate a digital signature with the same key/certificate.Is there

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.

Yes, I looked in the previous questions and there is no workaround provided even though Adobe marked the question as answered. I need to fill out the W-9 and the date section is not fillable. When I sign all it adds is my signature without a date and there does not seem to be any "Type" tool that will allow me to add a date to the date section. So how do I get a date on there? This is ridiculous. Ive now spent 30 minutes trying to add a date to the damn form supplied by the IRS. WHY? WHY? WHY? Can someone at least suggest some other software that will allow me to fill, sign and DATE the forms supplied by IRS?

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
