1. ID 21.2
2. Open a file made before the latest Windows update, its fonts will now be the incorrect version and appear as missing
3. InDesign should use the installed font
4. It's necessary to find/replace fonts on every file before it can be used. This also causes scripting issues.

This also effects Library files made before the OS update.

It appears Windows updated TNR and Calibri with the last few updates and this is causing issues with InDesign. ID is the only Adobe product affected by this problem. The others (AI, PS and Pr) seem fine. The version of Windows is 26200.7840.

Screenshot attached. Calibri (OTF) is not a font we've ever used, and doesn't exist. The correct font is still called Calibri, so the replacement is Calibri (OTF) -> Calibri. This is for the entire family.

This problem also affects Times New Roman.

Should also mention that this exact problem exists on 5 different machines all running the same versions.

Thank you.

Same problem here. Especially the Calibri font family is causing us issues. Hope you can fix it soon!

Any word on this?? We're approaching four months without a resolution to this issue...

I posted a bug similar to this one, only my bug was about the Calibri typeface. I was asked to vote on this posting as well.

2. This morning, Windows installed a major update (including firmware). My system is now running on Windows 11 Pro, Version 25H2, OS build 26200.7840 and has Windows Feature Experience Pack 1000.26100.291.0. When I tried to open InDesign, it wouldn't open. I followed the instructions from this post (https://community.adobe.com/questions-671/indesign-v21-not-starting-after-update-win-11-897997) and uninstalled all of my Microsoft Visual C Redistributable Packages and reinstalled them from the link posted by Anubhav M 3 months ago.

That (seemingly) solved the problem, but when I opened an existing InDesign file, I got an error message telling me that all of my fonts were missing. It listed the missing font as Calibri (OTF). I updated the font to the version of Calibri that was extant on my computer, and that seemed to solve the missing fonts problem.

However, I just tried exporting my InDesign file to a PDF, and in Background Tasks it has been stuck on Adding Font--trying to add Calibri Italic, Calibri Bold and Calibri Regular for at least 45 minutes now. The Export to PDF function is queued behind the adding font function, so essentially I am unable to export a PDF.

3. I expected that when I opened an InDesign document that was working last Friday, I would not receive a missing font message. And once I received a missing font message and changed fonts, I expected that the program would be able to create a PDF as usual.

4. See above

5. I have attached a screenshot of the background tasks window. I can upload a copy of the file if you would like to troubleshoot it.

I am an Adobe InDesign trainer and my client uses the system font Calibri for their files. Every time they open some files, the fonts are missing, but in older files they are not. The fonts are definitely installed. I had the same problem for a while. I've had 2 tickets open with Adobe and nobody can resolve it. The last Adobe rep informed me it was due to the Windows Security update from November 2025 (2025-11 KB506 8861), he asked me to uninstall it from my machine, after I did the problem went away. But I cannot expect the client team to do this as a solution. Windows security updates are essential and their IT team won't allow it. Please give us an ETA as to when this issue will be resolved! Thanks!

Could you please help me uninstall security update KB5068861? Is it still possible? I didn't manage.

I've had my Windows updates turned off for the last couple months, thanks adobe... But somehow i still got an update. The update KB5074109 has installed a different version of TNR. Adobe get your act together! AT THE VERY LEAST you should have the option to remember the font mapping preference for future documents so we don't have to change the font for EVERY document!

This issue is still happening with the latest Windows Security Update, KB5074109. Fonts are fine prior to the update being installed and after, they show as missing. If the update is uninstalled, fonts are working again.

Following the Dec 2025 CU (KB5072033) for Windows being installed, our Publishing Team reported Adobe InDesign was reporting "missing font" errors (for the Times New Roman font) in all files.

Our organisation had upgraded from Windows 10 to Windows 11 in Nov. The Windows 11 image had the Oct 2025 CU (originally Oct 14 KB5066835 which was superseded by Oct 20 KB5070773) and there were no issues with InDesign.

It would appear this community started reporting issues following the Nov 2025 CU (KB5068861) for Windows 11.

We are using the following steps (which we have scripted) as a workaround:

1. Copy the four TNR font files from C:\Windows\Fonts directory on a Windows 11 computer running Oct 2025 CU to a network share. Each file has the version 7.05.
- times.ttf
- timesbd.ttf
- timesbi.ttf
- timesi.ttf

2. For an affected computer, get all users to sign out. This is important otherwise the font files will be locked by system.

3. From a remote computer using an admin account:
a. Take ownership of the four TNF font files (e.g. takeown /F \\<computer>\c$\Windows\Fonts\times.ttf)
b. Grant full access to the four TNF font files for administrators (e.g. \\<computer>\c$\Windows\Fonts\times.ttf /E /G Administrators:F
c. Copy the four font files from network share to affected computer (e.g. copy /Y "<FONTSOURCE>\times.ttf" "\\<computer>\c$\Windows\Fonts")
d. Restart computer (e.g. shutdown /r /m \\<computer> /t 5 /f

Other:
Pre Nov CU the TNR font version was 7.05
In Nov CU TNR font version went to 7.10
In Dec CU TNR font version went to 7.11

I've been having this issue with Segoe UI ever since I did the Microsoft Security Update KB5068861. My company won't allow me to uninstall it. And this is not something users can fix on our end. So, I'm stuck having to replace a font THAT I ALREADY HAVE INSTALLED for every document this font it in, which by the way is hundreds of documents. My company uses this font in every single document. This is not only affecting Segoe UI but also Times New Roman, one of the most widely used fonts. I find it ridiculous and unacceptable that Adobe has known about this issue since November and still hasn't fixed it. Adobe is a BILLION-dollar company worth $141.93B, yet is too incompetent to fix a worldwide issue and has given no updates in the 45 days it's been aware of this? It seems Adobe prioritizes enriching executives and shareholders over maintaining its software to the highest standard for its customers that are already paying a ridiculous amount in subscription fees.

I'm having the same issue. Ever since the latest InDesign update, I get a missing font message for Times New Roman, even though it exists. It tells me that Times New Roman (OTF) and all its typefaces aren't available. I have to replace them with Times New Roman that is already installed. I have several hundred documents using Times New Roman, so simply replacing is not a good long term option.
I had our IT work on it today for several hours, and it was determined to be an Adobe issue, not a MicroSoft issue. We tried updating to the latest Adobe InDesign, and that failed to solve the issue as well.
I have a video screenshot--not sure it attached here--if you need it.

I also have this same problem but cannot go back and uninstall the original problem security update. Is there a solution to this problem yet? Do I have to reinstall the OS and everything else to get back to the point where I can choose not to install the security update(s)? Just "not installing security updates" cannot be the final solution to this problem.

Also having this problem. Computer updates are determined by my employer, so I cannot backtrack on them to test that. This issue happens upon opening nearly any InDesign file that was previously created - it claims it cannot find Times New Roman (OTF) Regular, despite me having used the TT version if anything and, most of the time, not having this font on the file at all.

What triggers this issue for me is turning on Windows Update on my Windows 11 PC. It appears to be security updates that are causing the issue, so not ideal to have to keep those switched off. At first it was Security update KB5068861 and then, on Dec. 20, when I turned updates back on, it was Security update KB5072033 that caused the issue. All Indesign files are fine prior to the update install. After the updates are installed, Times New Roman in all Indesign files throws a missing font error. Upon uninstalling the Windows security update, all Indesign files are once again fine. It does not appear to be specific files, just the font itself. I've attached screenshots of the font info prior to installing the Windows Security update and what is being shown after the Windows Security update is installed and Times New Roman is giving the missing font error.

This is related to the windows latest security update KB5068861. Installing it creates the font issues described. Uninstalling the security update fixes the issue but this needs a better resolution from Adobe and Microsoft.

I have numerous documents that use the times new roman ttf font, my windows 11 will not allow me to install the otf version required by indd v21.0. I need an urgent resolution to this problem. Please can you provide me with a date for a fix
