Windows Application Error Referenced Memory could not be written

[adminu31318584]

Hello,

I am having an issue with Adobe Acrobat Standard license when opening all PDF's. When I open the PDF's, I get the error in the attached image. I have tried uninstalling and reinstalling Adobe twice, updating Windows, rolling back the version of Adobe to DC June 2024 (24.002.20857) from DC Jul 2024 (24.002.20933), SFC, DISM, checked compatibility settings on .exe of the app, turned off protection mode in Adobe. Nothing seems to pop up in event viewer or Process monitor. Mind you, clicking OK on this pop-up does not close the application and does allow the PDF to be edited normally. Any help would be much appreciated.

The error if you can't see the picture is:

Windows - Application Error

The instruction at 0x0000000071C80670 referenced memory at 0x0000000071C80670. The memory could not be written. Click on OK to terminate the program.

This issue got fixed over a remote session with an Adobe support Tech. The fix was uninstalling Adobe Acrobat, deleting all folders/directories named "Adobe" on Local drive (Program Files, PF x86, Common Files, etc...), then finally using the "Adobe Cleanup Tool" (this step isn't too important if you deleted everything). After that, you should be able to reinstall it and the pop-up will no longer appear.

How did you do that? Any details would be very helpful

This trick did not work, but thanks for sharing. And so it continues...

We only seem to have the issue when opening Adobe pdf from emails.

Getting this error after updated from Windows 10 to Windows 11 24H2. Rolling back to Windows 10 isn't an option. 
Have uninstalled/re-installed Adobe. Have tried compatability mode and adjusted virtual memory.

Only happens when opening a PDF from an email attachment.

Not sure if this helps anyone but we were having this issue opening pdf files from outlook to adobe acrobat, 
Seems like the fix was to Disable New Adobe as well as Run Acrobat in compatibility mode for Windows 8, those 2 combined fixed our error

Not sure what you mean by disable new adobe. Tried the compatibility mode for Windows 8 alone and it did nothing but open to trying something since I'm out of ideas. If you could clearify what you mean by disabling new Adobe that would be great.
