Times New Roman TTF replaced with OTF in InDesign after Windows Security Update installed

Since this post seems to be marked as resolved after the Adobe Community update and it isn’t resolved, I’m creating a new post and linking to the old one. All the relevant information can be found here (at least all of the information that survived the Adobe Community update -- there are several missing posts).

Long story short -- when you install Windows Security updates, some system fonts -- Times New Roman for me -- throw a missing font error in InDesign. This error only goes away if you uninstall the Windows Security update. More detailed info can be found in the linked post.

This issue has been going on for literally months, since last November, and we’ve got bupkis to show for it -- less than bupkis now that some of the original posts have been nerfed with the Adobe Community update and the original thread appears dead. Adobe. Please. Help. This is beyond frustrating now...

Hi everyone,

Thanks for sharing the details here. I wanted to let you know that this is a known bug, and our product team is currently working on a fix. The issue appears related to recent Windows font updates, which changed how InDesign recognizes certain system fonts (like Times New Roman TTF vs OTF), causing missing font warnings in existing documents.

In the meantime, please consider upvoting and following the related UserVoice report here:
[ID-4272938] After installing a Windows 11 update, InDesign is unable to find the Times New Roman and Calibri fonts – Adobe InDesign

We appreciate your patience, and I’ll share updates here as soon as they’re available.

Has Adobe just given up on this?? To my observation, on a fully updated machine, these missing font errors are still occurring--no change in behavior at all--and I simply cannot go back and just change fonts on older files that are still integral to current work (a major book project that has been years in the making), even if there is a hack to make it possible to update system fonts.

I’ve been able to work around this by stopping updates on machine, but that cannot be a permanent solution…

Please update if you know anything. Thanks!

After Windows Security Update is installed

After uninstalling Windows Security Update

Can confirm as of today, Feb. 8, that this issue is still very much a problem. I installed the latest Windows updates including the security update and the same issue with the fonts happened. Uninstalling the Windows Security Update fixed the problem. Definitely looks like some sort of directory/filepath issue here…

As far as I understand, that’s the problematic Windows update that has been widely discussed recently. Although the problems it caused to most users are more severe than just missing fonts:

Plus, I believe Microsoft by now released a newer update that fixes the problems caused by the faulty update (albeit I don’t know if it applies to the font problem you describe.)

Is anyone from Adobe still working on this issue? I’d like to think so but haven’t seen any evidence of that in weeks. Adobe, please update!

Oh, and by the way, at the moment I do not have this problem with Times New Roman - I opened a 20-year-old InDesign file typeset in Times New Roman the other day without any problem. My version of Times New Roman is 7.11.

This does not just concern Times New Roman, but a number of other fonts as well.

This issue is emphatically not resolved! I had to restore my machine to early November in order to remove the problematic Windows update and have had to keep Windows updates turned off since then. That workaround has continued to function, but we cannot leave Windows updates off forever. Please, please get this resolved, Adobe!!

Also, I only recently joined the community--because of this very issue--and the community update mentioned above removed my identity from the community...which is a useful feature if you want to reduce complaints, I suppose...

Leaving Windows updates turned off is not an option for me, our Head of IT would give me a lot of grief if I did. Collaboration with someone using InDesign on a Mac coming up, let us see what happens when I get files from them. And this does not just concern Times New Roman.

Yes, there are definitely more fonts than Times New Roman that are affected by this issue. Also, I work on Windows at home and Mac in the office. “Fixing” the fonts on Windows using the Find/Replace font function and changing them from the “missing” TTF version to OTF versions, breaks the fonts on Mac for me, which is a big part of why this issue has been such a pain.
