Acrobat Reader

Any solutions?

Hello! Recently we have had a user encounter an error when using Adobe Acrobat Pro that states the following: Cannot find or create the font ‘Helvetica’. Some characters may not display or print correctly. I have manually ensured that this user has all Helvetica-related fonts installed on their device, and verified that other users are not having this issue when opening this document, so i’m unsure what else to do.  I have also repaired and reinstalled Adobe Acrobat.  Any insight would be greatly appreciated. 

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

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

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.

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.

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

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?

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.  

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. 

OK, this is getting no response at all from Adobe, so I am going to ask this question again as, while one of the 2 other posts on this subject says “answered” it is NOT answered. So, I am going to open a 3rd post on this subject to see if someone at Adobe will care to comment. ALL of the links in Reader open in Edge and not the default browser (Chrome in my case). When I say all, I mean even the help links like the link I opened to get to this forum (yes, I’m in edge now just trying to get the real answer) and the one in the image below:And yes, I have tried EVERYTHING referenced in all the attempts to fix this when you Google the issue. NOTHING fixes this “bug”, but surely someone out there knows how to fix this so we can all get on with life. Thanks - John

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....

Hi Everyone, I am currently Downloading PDF Files from my Gmail account to my Desktop.Up until today, I was able to Download these files no problem. Today however, everytime that a PDF Files completes downloading from Gmail to my Desktop, Adobe Acrobat Automatically Opens the file on my Computer. This is Driving me MAD! Is there any way to stop this from happening? I've attached a file that I got from a Reddit post - where other people were having this issue.It seems that in the past, that there was a check-box option in Acrobat Reader under Edit -> Preferences -> General  to turn off this annoying features. But this option is missing on my Acrobat Reader.

Hi all. I'm posting this in the hopes that it might help someone else out that may have the same symptom. Last week, my Adobe Reader stopped printing. Nothing I did produced any result. Not hitting the print icon. Not hitting CTRL+P. Not selecting "print" from the drop-down menu. There was no error message. No nothing. It was as if I hadn't clicked anything. I tried repairing the installation, no help. I've rebooted the computer many times over the last couple weeks. Here's what finally fixed it. On a whim, I went to Windows Explorer, right-clicked on the PDF file, and selected "print" from Explorers context menu. Adobe flashed open for a sec, and the document printed. Now, Adobe Reader prints as it always used to do. There must have been some little "glitch" or something going on.Problem solved. Hope this helps someone else.Artie
