ADC-4489673 error when opening pdf's from New Outlook Instruction can not be read

Report · Aug 21, 2025

I tried to do a support chat today and the rep after I got disconnected frrom one the day before said there is a known issue the ADC-4489673 and it is being worked one. If nothing is heard within 2-3 days to check back. I search and haven't seen anything on this issue so if that's case why doesn't adobe start to post known issues so people can just respond and add themselves to existing issue tickets and notification when it's solved and steps to fix it?

THE INSTRUCTION AT 0x0000###### rerferenced memory at 0x000000000. The memory could not be read.

Click ok to terminate the program.

I have a case already open. So is this correct on the Incident#? Are there steps to follow as the rep, (rakesh) didn't provide any support and just said there was active research into the case already.

Hi stop-outsourcingstuff,

It is just a workaround that worked for some of the users. This might or might not work, and the product team is still working on the fix.
