I wanted to check in on this. I thought this was an Adobe Acrobat error but then found that I get a similar error ONLY when opening a PDF with Acrobat through Zotero 7. I've tried all of the Adobe fixes for this and it seems to reside only in Zotero 7. If I open a PDF that is on any other drive on my PC (OneDrive, Dropbox, my C:/) with Acrobat it does not reproduce. It only happens when opening a PDF with Zotero 7 and it happens with every PDF. So, if I open one PDF and get the error, but then open another (adding a tab to Acrobat) I get the error again. As Younes.ab notes - I can click cancel and the PDF works ok, but this is super annoying. Screenshot of error attached.

Any fixes yet?

I wanted to note that I just found some interesting details about this bug for me. It does not flag the reference memory error when I am using Adobe Acrobat 2017 on my desktop. However, on my laptop I am using Adobe Acrobat Pro (v. 2024.005.20320 | 64-bit), which is currently installed via Adobe's new online log-in tools (now used by my EDU institution), rather than a fully "owned" copy from previous Adobe software protocols.

So, I just found that I get the referenced memory error on all PDFs if I do not first open Acrobat Pro. That is, if the Acrobat Pro software IS NOT open on my Windows 11 laptop, any PDF opened via my Zotero library that subsequently initiates Acrobat Pro, will produce the referenced memory error for the first PDF (that starts the software) and any after it. However, I have found that if I open Acrobat Pro FIRST, but do not open any PDF, and THEN I open PDFs directly from my Zotero library, I no longer get the referenced memory error.

This is still an annoying little bug but I hope this helps identify the issue for a future fix! I'm still very much liking the new Zotero 7.

I started using Zotero this week, and have also encountered the problem reported by edward.henry:. Never encountered this problem before, and I use many programs that launch Adobe Acrobat (including EndNote for over a decade).

1. If Zotero is the first application to open Adobe Acrobat, then Windows will throw that annoying application error at that time and subsequently every time anything opens a pdf file (e.g., opening a pdf file from your desktop, from Zotero, from EndNote... )

2. If Adobe Acrobat is launched NOT by Zotero (e.g., you opened Acrobat directly from Windows before launching a pdf file from Zotero), then Windows is happy at time of launch and whenever a PDF file is opened, including by/from Zotero.

Sorry, but all fingers point to how Zotero invokes Acrobat as the culprit.

I'm also getting the problem on a new high spec laptop.
I've tried all types of troubleshooting I could find for similar Adobe errors but the only thing that helped was running Adobe in Windows 8 compatibility mode. I, however, don't want to run Adobe like that.

It seems like the little work around of opening Adobe first seems to also be working as mentioned above so I fully agree it's something to do with Zotero launching Adobe.

Just chiming in to say this has also been happening to me for the past few weeks. I did try to uninstall and reinstall Adobe. I'm running 7.0.16 (64-bit) Zotero. I am a federal employee so I don't have control over the exact way Adobe or Windows works or is installed. I am on Windows 11 on a laptop that's not very old (a few years?). The workaround to open a blank instance of Adobe first, then open files from Zotero removes the (very annoying) memory error. As with others, the memory error doesn't actually prevent me from doing anything. If I open files from Zotero without starting Adobe first, I get the error for every PDF I open. And as others have said, if I open a random PDF from my computer, I don't get the error - it's definitely isolated to Zotero.

That said, thanks to those who posted and commented because I can live with the workaround for now! And I found this pretty easily searching on duckduckgo.

Got it. Thanks!

Thanks.
