有人知道為什麼螢光標示檔案後，在Google雲端硬碟變成這樣？原本前幾天的都不會！突然這兩天的變成這樣？這兩天我都在研究如何能夠讓字型嵌入檔案，是動到了什麼設定？

Does anyone know why text highlighted with the Adobe PDF highlighter pen appears as black outlines with yellow comments when viewed in Google Drive?It wasn't happening a few days ago, but it suddenly started showing up like this over the past two days! During these two days, I've been researching how to embed fonts into files—did I accidentally change some settings?  

Hello, I am currently experiencing issues with Adobe Acrobat using 20+ GB of RAM when trying to use any acrobat functions from organizing pages to OCR. These are not large files (>100MB). I’ve been able to consistently reproduce the issue with multiple different files and on multiple devices including PCs fresh out of the box.  I have reproduced the issue on W11 24H2 and 25H2, On Acrobat Version 25.001.20997. Tested it on both 32 and 64bit. Uninstalled and reinstalled acrobat. Tried doing a full reinstall of the computers OS. Protected mode is disabled.  Systems have 32GB of DDR5 RAM, an i7 with an M2 SSD. It seems like from my research this is just a consistent issue with Adobe as I’ve seen reports of this same issue going back 10 years. Is there ever going to be a fix?

I’m having an issue that started about two weeks ago where anytime I use the add text comment tool and click on the page to write something this black box appears.  I can type but can’t see what I’m typing. If I click off the comment I can see the text fine but if I click on it to edit it the black box comes back.  I can also highlight the text and see the words but the black box remains on any part not highlighted. Acrobat is updated, windows, and my graphics card are all updated.  I’ve also uninstalled and reinstalled acrobat entirely.  The problem started randomly.  I’ve also messed with the rendering settings in preferences.  Any ideas?

Need some assistance editing an incorrect email using the Adobe Sign tool in Adobe Acrobat Pro DC. I have the latest Adobe Acrobat Pro installed on my Windows machine. 

Much of our catalogue of sheet music has covers created as A3 landscape spreads (front and back). When collated, the cover PDF is inserted as first and last pages. The first is cropped on the left to A4, and the back cover cropped right. For years this has worked fine.Now when I print a booklet, the covers look fine on screen preview, but when printed the whole A3 cover is reduced at rotated 90 degrees to fit on A4 (same front and back). If I open the PDF in another program (e.g. PDFX) there is no problem, so I assume error is with Adobe - perhaps a recent update?At the same time, where covers have a white background they are printing out with a slight tint. Likewise with some, but not all, pages. Again, this wasn’t a problem before. Why?I don’t know how to start fixing these - any suggestions please? Sarah 

Tengo un problema para firmar PDFs en Adobe Acrobat DC / Reader en macOS usando un token ePass2003 / FEITIAN / Macroseguridad.El módulo PKCS#11 que tengo cargado en Adobe es: /usr/local/lib/libcastle.1.0.0.dylibAdobe reconoce el token/certificado, pero al momento de firmar aparece: Error PKCS#11Código de error: 0x30También probé con AutoFirma y aparece un error relacionado con que no encuentra la clave privada asociada al certificado.Ya probé reiniciar la Mac, reinstalar Adobe, quitar y volver a cargar el módulo PKCS#11, desconectar/reconectar el token y revisar el certificado en el llavero de macOS. ¿Alguien logró hacer funcionar ePass2003 en Adobe Acrobat sobre macOS?

I had to reinstall Adobe Acrobat Professional 12.0 Win UE otherwise known as Adobe Professional DCSoftware installs fine after I enter the Product Serial number.  I have both the Product Code and Serial Number.When I launch the application, it asks me to login to my adobe account using the QR code it presents to activate the software. I do that and it says successfulI then go back to launch the application, and it again asks me to activate the software.  I have tried 10 times.  No luck. Any suggestions how to get around this issue?

Hello,The recent 12-Jan-2026 seems to have changed how highlighting works in the comment tool. It used to be possible to highlight in a blank area , for example under a block of text or music stave, then add text notes. It would also straighten out the drawn highlighter line, which was useful. Since the update, highlight trys to find adjacent text or objects and selects them, often incorrectly. It no longer highlights a length of text or blank space. I find it far less useful now than it was. Please revert to how it used to behave prior to the recent update. I can (sort of) do what I want using the draw tool, setting colour and opacity to get a similar effect, but it no longer straigtens out the drawn line. It also means setting the draw tool to do what I want everytime I use it. Thanks, Colin.

For some reason the tool Compare files causes Acrobat to freeze and I then have to terminate the program. I use it a lot but now it doesn’t work. Anyone who knows why?

Hi all,We’re experiencing an ongoing and very disruptive issue with Adobe Acrobat when reviewing and digitally signing PDFs.What’s happening:While reviewing multiple PDFs and applying digital signatures, Acrobat frequently glitches.After signing and saving, the signature disappears with no error message.This forces users to re-open the document and re-sign, sometimes multiple times.Saving, editing, and signing actions are often slow or delayed, which seems related.Impact:PDFs generated by instruments must be reviewed and digitally signed in Acrobat.It can take 1 to 5 attempts for a signature to actually persist.In ~99% of cases, there is no warning or error — the signature simply vanishes after save.Environment notes:Issue occurs across multiple documents and sessions.Happens during normal review/sign workflows (not concurrent editing).Extremely time-consuming and risky for compliance-related documents.Has anyone else encountered this?Any known causes (cloud sync, autosave, incremental

Several users have reported that the Adobe Acrobat application closes automatically within 4–5 seconds of launching. We've found that manually clearing Adobe-related cached credentials from the Windows Credential Manager resolves the issue temporarily. However, this problem keeps recurring. Has anyone encountered this behavior before or found a permanent fix for it? Any insights or recommended solutions would be greatly appreciated 

In a new PDF file of a contract, text not showing on completed PDF from Docusign. Getting the error code: There was an error processing a page. Bad font object or font descriptor object. How do I fix? PDF works in Apple Preview

I have a current subscription to Acrobat and I'd been using it without any issues for years. Today, the app installed on my computer is not allowing me to edit a document and instead forcing me to upgrade to a Pro subscription with other apps. Editing a pdf is definitely included in my subscription, so why am I forced to upgrade? I can't select to opt out or anything either and it's hindering my work. Can someone tell me how I can stop this?

Acrobat 2d measuring tools 'snap to point' options not working. This has recently stopped working (Aug 2026). It's not just my version either, it's also stopped working for everyone else I have spoken to who uses this tool.

Looking at everything on line.  Nothing is working. My accountant put my last year’s returns under a password. Which I have. But now that I want to share them with a new accountant, I just want it easy and simple. NO password. How do I do it?  All I see is “protect” no “remove”.  Thank you!!  SO frustrating. And again, YES I have Adobe Acrobat.

My Adobe Acrobat installed app suddenly stopped working.I am using a MacBook M1 (Ventura 13.1) and have the latest version of the app.Everything was working fine for all the months I’ve been using it. One day, I was working normally using the app, when I was finished I closed it and about 30mins - 1h later when I came back to re-use it on something else it wouldn’t open (one hop on the slide-bar and that’s it). I tried everything from adjusting settings on my computer to cleaning, deleting and re-downloading the app - nothing…  Any ideas of what to do??

Hello,I want to create a Custom Dynamic stamp that uses the current day’s date on the date the stamp is used, and shows the date using a 3-letter month in all caps, then the day, then the year: MMM dd, yyyy. For example, 1/1/2026 should show up as “JAN 01, 2026”From Acrobat Pro DC (Ver 2026.001.21691), Win 11, I did the following:All tools > Add a stamp > Custom stamps > Create.

I’m an IT technician writing this up on behalf of our own support desk. Over the past several months, we’ve seen a large influx of users (must be close to triple figures at this point) reporting that they’re unable to open PDFs. When investigating, we find that Acrobat is creating a background process every time an attempt is made to open a PDF:But it doesn’t actually open anything. From the user’s perspective, nothing happens. When this is occurring, the Acrobat client itself also will not load on-screen when opened via the Start Menu or desktop shortcuts, and there are no associated errors at all. The only way to correct this is to close all the Acrobat processes, which will make it start working normally. The problem is that this is only a temporary fix and it soon starts to reoccur for the user.Some additional info:All of our clients work inside Citrix VDIs, a majority of which run Windows 11 24H2. This has been occurring for months, so affecting multiple Acrobat versions (last con
