Based on the information provided, and since the feedback you have received is more tied to the mobile app.  I would recommend suggesting to your users to use Liquid Mode: https://adobe.ly/4fVXAhi   Adobe Liquid Mode is an AI-powered mobile reading experience that reformats PDFs on the fly for easy reading on phones and tablets. It intelligently reflows text, adjusts layouts, enables zoomable images and collapsible content sections, and auto-generates a navigable outline for seamless document navigation.   In essence, Liquid Mode transforms static PDF pages into fluid, mobile-friendly content without altering the original file, delivering a smoother, accessible experience across mobile devices.   Let us know if you have further questions. In Acrobat, there is no such feature that will allow you to export mobile-friendly or compatible PDF-like videos for small screen sizes, etc. Hence, liquid mode is your option.   Best regards, Tariq | Adobe Community Team ...

Hi @luke_9214,   Thanks for reaching out! The message you’re seeing — “This PDF file is protected… The reader you are using does not support opening files protected by Microsoft Office” — indicates that the PDFs are protected using Microsoft Information Protection (MIP) / RMS encryption, not Acrobat’s own password/security features.   That usually happens when: The PDFs were created/exported from Word, Excel, Outlook, or another Office app that had sensitivity labels or IRM protection applied (sometimes by company policy, even if you didn’t set it manually). The files were then attached to an email or shared, and Acrobat (or most standard PDF readers) cannot open them because they require Microsoft’s own viewer.   A couple of clarifications that would help narrow this down: How were the PDFs created — directly exported from an Office app, or printed to PDF? Are you opening them in Adobe Acrobat/Reader, or in another viewer? Are you on a work account (with Microsoft 365) that may have policies automatically applying protection?     Next steps you can try: If you’re on Windows, try opening the PDFs with Microsoft Edge or Office itself (those support MIP-protected PDFs). If you want these files to be readable in Acrobat/Reader, you’ll need to export them without MIP protection — typically by saving/exporting again from Office without sensitivity labels or with protection turned off (if your IT policies allow it). If this is on a corporate device, your IT team may have set rules that automatically add protection. In that case, best to check with them. Let us know how it works.

Hi @Michael305062150zf6,   Thanks for sharing the details. I understand how frustrating it must be to see a Pantone color suddenly shift after so many years of following the same process. Let’s try to narrow this down together.   To help us investigate further, could you please check the following: Acrobat Version – https://adobe.ly/3PQQ7nE Where the Shift Appears – Does Pantone 152 U look green only in Acrobat’s on-screen preview, or does it also appear green when you print/export the PDF? Output Preview Check – If you go to Tools > Print Production > Output Preview, does it still list Pantone 152 U as a spot color plate, or has it been converted to CMYK? Comparison Across Apps—If you open the same PDF in another viewer (for example, Acrobat Reader or Acrobat Web: https://adobe.ly/4fUuP4R ), does the color still shift? Sample File – If possible, could you share a sample PDF (even a single test page) where Pantone 152 U shows up incorrectly? This would really help us reproduce the behavior. And the source file.    These checks will help us determine whether the change is occurring during Acrobat’s rendering or if the file itself is being altered. Once we have this information, we can loop in the right team for a deeper look.   Thanks again for flagging this! Best regards, Tariq | Adobe Community Team | Meet Acrobat Studio ... View more

Hi @ChickenMan67,   Thanks for reaching out. Sorry for the troubled experience. As per the tech specs for Reader's latest version, Win 7 is a supported OS, and it should work fine on your machine.  Here are the tech specs details: https://adobe.ly/3UJ9ZM7. Please validate if the machine has Windows 7 with (SP - service pack)-1.  Windows 7 SP1 (32-bit and 64-bit) Restart your machine once. Then, use this link again: https://adobe.ly/3JwZqcy, try installing Reader, and let us know how it works. If possible, please share a video of the workflow.  Best regards, Tariq | Adobe Community Team | Meet Acrobat Studio ... View more

Hi @raphael_2525,    Thanks for sharing the file.      When I open the file, the error message for the font "ULPHJY +Arial, Bold" appears. Since this file was created with a third-party app, it likely used a custom font. While Acrobat attempts to render the file, the font does not seem to be properly embedded, hence the error.  After I used the Preflight font fix-up, the file opened, and those dotted lines turned into text. I know it may not fulfil your requirement that a font face be used, but now it is clear the issue is with the file, not with the app.     Please check the file attached that I fixed.    FYI... Why does Acrobat show font issues while browsers/other apps render fine 1. Acrobat is stricter about fonts Acrobat and Reader strictly follow the PDF specification. If a PDF doesn’t embed fonts properly, Acrobat tries to use the exact system font (or substitute one) → If a font is missing, you’ll see errors like “Cannot find or create the font.” Browsers (Chrome, Edge, Firefox) or other viewers are more forgiving, and silently substitute with any available font without warning.   2. Font embedding differences If the PDF creator only partially embedded fonts or didn’t embed them at all, Acrobat notices this and highlights the issue. Browsers just render with a fallback font that “looks close enough.”   3. Transparency and text rendering Acrobat uses a full PostScript and PDF engine to render content. Many other viewers use lightweight rendering libraries (like PDFium in Chrome) that rasterize text differently, masking font issues.   4. Security / Licensing compliance Acrobat respects font licensing more strictly. Some fonts cannot legally be embedded. Acrobat warns you.     Best regards, Tariq | Adobe Community Team | Meet Acrobat Studio ... View more

Hi @riley_6020, Please keep us updated on how it works after using the cleaner tool.  Also, you need to check if the Thumbnail preview preference is checked.    How to check:   1. Launch Acrobat. 2. Press Ctrl + K > Preferences > General, and check "Enable PDF thumbnail previews in Windows Explorer." Then click OK. 3. Acrobat will restart. Wait for a minute.  4. Try selecting files only and check context menu options. (Select PDF files only)     Let us know how it works. Best regards, Tariq | Adobe Community Team ... View more

Hi @angelica_5902,   That’s a great question — thank you for reaching out!  @PDF Automation Station has pointed you in the right direction. If you want to take the JavaScript route.   Here’s a sample script you can try in the Custom Keystroke Script: if (!event.willCommit) {     // Only allow digits     event.change = event.change.replace(/\D/g, "");     var v = event.value + event.change;     // Limit to 8 digits     v = v.substring(0, 8);     // Insert slashes automatically     if (v.length > 2) v = v.substring(0,2) + "/" + v.substring(2);     if (v.length > 5) v = v.substring(0,5) + "/" + v.substring(5);     event.rc = true;     event.value = v; }   A couple of tips: Place this code in the Custom Keystroke Script for the date field (Properties > Format > Custom). You may still want to add a validation script to check that the final date is valid (for example, not 02/30/2025). Acrobat JavaScript runs in a sandboxed way, so testing step by step (typing slowly) helps you debug.   :warning: Disclaimer: Adobe does not provide official support for custom JavaScript in PDFs. The script above is a community-suggested approach and represents the best possible support we can provide here in the forums.   Since you mentioned you’re a novice with Acrobat JavaScript, don’t worry. Experimenting with these small snippets is the best way to learn!   Best regards, Tariq | Adobe Community Team | Meet Acrobat Studio ... View more

Hello,    It is not recommended to use both Reader and Acrobat.  To avoid this issue, Adobe has released the Unified installer to avoid this conflict. As your company or employer updates to the new versions, there will be only one app that will exist on the machine.    For more information on the unified installer, please read this article: https://adobe.ly/4mTkTuz   Best regards, Tariq | Adobe Community Team | Meet Acrobat Studio ...
