Hi there,
Running Windows 11, up-to-date system and up-to-date Creative Cloud and Adobe Acrobat DC. I have my preview pane visible when going through my files, and sometime in the last 2 weeks PDFs no longer show up in the preview pane. Instead, windows explorer freezes for a few seconds and then shows an Adobe Acrobat "An Internal Error Occured" pop-up. I tried clearing out my temporary files, and tried creating a "2022" folder in C:\Users\(user)\AppData\Local\Adobe\Acrobat\ which was suggested in this thread. Neither worked. All other file types (.jpg, .doc, etc.) show up in the preview pane just fine. Any suggestions?
I FOUND A SOLUTION.
I had to go C:\Users\[me]\AppData\Local and right click the Adobe folder, click properties and go to security tab. I had a bunch of left-over "Account Unknown" listed besides my three main ones (System, [me], Admin). I deleted all the account unknowns.
That fixed it for me.
This worked, for me! (thank god, what a pain in the a**)
I couldn't find the "AppData" folder, I ended up finding it by clicking "view", then "show" and then toggling on "hidden files".
Me paso lo mismo, entre en la ruto que colocaron y le saque los permisos heredados y borre los los desconocidos y hasta ahora funciona

checked everything. No "unknown" accounts (only SYSTEM, [me] and Admin. The error is still occuring. Any ideas?

This does not work for me as there are only 3 accounts, admin, me and system. Although the disabling the Preview pane stps the error, it means I can't use the preview pane which is a useful tool. Only a work around, not a solution. The problem only occurs for me when clicking on a PDF that has onedrive syncing it. Not my local machine. Microsoft seems to not have any support for this but it's clearly an issue on both sides. Any other solutions other than already shared? Also, what is the cause of it?

Hey just wanted to come here and say that while this solution did not work for me, I deleted all files located at "C:\Users\[me]\AppData\Local and right click the Adobe folder" and just deleted them all, then tried running adobe and it finally worked fine. Took me hours of work trying to figure out what could be the issue.
uninstalling and reinstalling didn't work, downloading the latest patch didn't work, permissions were fine, no unknown users in the permissions tab. deleting temp folder didn't work. What finally got this bug resolved for me was deleting that entire file, it rebuilt when i relaunched adobe. I just want to say that if you get an error saying that the file is in use, use task manager to close all instances of adobe including the cloud app, and the update messenger app.

I've tried all of the solutions listed here. I'm running Windows 11, completely upto date system. I've worked out it's an Adobe Acrobat DC issue by removing Adobe Acrobat and letting the system fallback to Foxit phantom pdf which was my previous default software. The moment I did this, all of the pdf's can be previewed without a fuss.
I'm at a complete loss of how to resolve this for now and don't want to waste more time than I already have.

Hi Josholo,
Adobe hasn't been very helpful in this thread. I'm not sure how to apply the Account Unknown fix in Windows 11. Maybe start a new discussion?
If I find any helpful tips or solutions I'll post them here for you.
As a quick fix, you can disable the preview pane in your folders, but as a designer, it's almost as frustrating as the errors.

Its a very frusting error, especially if you are doing any design and you have alot of files. The preview screen can really help with workflow and efficiency.
For now, using the default system viewer without Adobe Acrobat DC installed is getting me out of trouble and working without a fuss. When i'm not buried in projects, I'll revisit this one and see if I can resolve.
Strange that the preview works inside application like outlook but not in explorer. I unfortunatley don't have all of these 'unknown accounts' which has stumped as to the source of the error.

That is strange, are you sure you looked in the right folder?
It has happened that people have gone into the wrong folder, did you type out the file path or just click through? C:\Users\[username]\AppData\Local and then right-click on the Adobe folder?
Have you tried posting on a Microsoft forum?
I've attached the 5-step screenshots that I made in case you missed them.

Thanks @RedFeathers I had another go but the error still persists. I've escalated to our own IT department to see if they can find any strange conflicts that are perhaps linked to company app security protocols and all that. I don't have any of the 'anonymous' users in any area at all. All users have full permissions too. Very strange and very frustrating that i can't seem to use the most simple product out of the adobe suite due to a consistent error at preview pdf which also then slows up my computer to display the 'internal error occurred' message.

May be ask in a Microsoft forum?
These fora are basically user to user fora. When Adobe employees jump in, they are doing that in their "free" time too. Users helping users is sometimes more effective than calling support, especially for such a strange behaviour.

Hi Abambo, thanks for clearing that up, I was under the impression that there are Adobe staff moderating the forums and looking out for possible bugs for future product updates. Keep well!

Take a bow! I've been struggling with no preview for months and then the 'Internal Error' started and it's totally stuffed up my workflow. Asked my tech husband to look at it and other solutions didn't work. He was going to do a reinstall of my computer tonight, but now he doesn't have to... and he knows how to fix it for others! Thank you, thank you, thank you!!!

This is driving me crazy! Have restarted, reinstalled, updated software... even got a new laptop! It's a work issued and had another problem but when I was reset back up with my credentials the error came with it. Very frstrating and confusing
