"An Internal Error Occured" when clicking on a PDF and Windows Explorer preview pane is showing.

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.

Try updating your Adobe creative cloud and apps, and trying a Windows update. It's working fine for me now!

Well, for some reason it's fixed now. Not sure if it was a Windows update or Creative Cloud update but the preview pane is showing PDFs fine now. Thanks!

Either an Adobe update fixed it or a Windows update did. Now I can view PDFs in the preview pane again without any issues.

Well, unfortunately it's back to showing an Adobe Acrobat "An Internal Error Occured" pop-up. Which is so frustrating. I checked both Creative Cloud and Windows for updates and I'm up-to-date. No one from Adobe Support has chimed in, so I guess I just have to wait until another update fixes it 😞 Keep trying!

Thanks for the reply!

 

I created another post about this issue so maybe that will help motivate their support team...

Same issue constantly! I have no idea where to send Adobe support my crash dumpfile as they don't even list the location on the help file!

I'm on Windows 10 and getting this too. I thought it could be a windows display setting that was disabled, but I can't find anything that would seem to be related to this error.

Has anyone else had this issue resolved with an update yet?

I see that an Adobe team member mentioned working on a fix for this issue on the 15th of Sept, but that's just over a month ago so I've left a comment on that thread for feedback.

I'm hesitant to try installing the 32-bit version as I've had issues with other software in 32-bit.
