Error message "The instruction at 0x000000006605D107 referenced memory [...]"

[Istvan36826407eb7j]

When closing some PDF documents the following error appears:

"The instruction at 0x000000006605D107 referenced memory at 0x0000000000000500. The memory could not be read."

This doesn't happen to all documents, but I've encountered this message on many of them, and only when closing.

Running Adobe Acrobat Reader Version 2024.002.20687 | 64-bit on Windows 10 Pro for Workstations 22H2

Any ideas what could be the culprit?

Below the log from WinDbg.

[Istvan36826407eb7j]

The problem was solved by installing an older version of Adobe Acrobat Reader.... if anyone has the same problem.

[Istvan36826407eb7j]

It seems it's a bug in the actual version....so after installing the older version, the automatic update has to be disabled...for the time beeing....till the problem gets fixed.

Hi,

We have the same problem. Is there any insight into when this will be resolved? This will influence the choice to downgrade.

Hi @Istvan36826407eb7j @Félix3560 @icts30471004 

Hope you are doing well.

Our engineering team requires the dump file for the crash to further investigate the issue, please share the requested dump file so we can isolate the issue for the fix.

[Istvan36826407eb7j]

Hi Amal,

I've attached the dump file.

[Serene_nature15C3]

Hi @Istvan36826407eb7j 

checked the dump file that you have provided and it seems to be invalid. We are getting the below error while opening it in WinDbg and Visual studio:

Could you please provide a valid dump for the crash so that we can investigate the same?

~Amal

[Jamar37615964h1um]

I'm getting a similar error message with the same behavior. Will the fix being worked on apply to me even though the numbers I have for '0x00' are different?

[Serene_nature15C3]

Hi there

Our engineering team is still reviewing this issue. We will share the update as soon as we get any information.

~Amal

[icts30471004]

After 6 weeks of silence, is there any progress about this issue?

[Serene_nature15C3]

Hi there

Thank you for your patience. Our engineering team is actively working on resolving the issue. Unfortunately, we don't have a fixed timeline yet.

We will update you as soon as we have more information.

~Amal

[Istvan36826407eb7j]

Unfortunately the downgrading fix doesn't last much, since the automatic update is re-enabled for some reason...even if it's disabled from services and task scheduler.

However, installing the latest 32bit version seems to fix the problem.

This version can be downloaded as following:

1. On the download page click on "More download options"

2. In the pop-up window click on "Version" and select the last option.

[Istvan36826407eb7j]

It seems that the 64Bit version can also be fixed by disabling the new interface.

[matt_6869]

Didn't work for me unfortunately. Unbelievable how long it's taking them to fix this bug - not a confidence inspiring experience for a program I just agreed to pay for.

[Sean38936642yrq2]

Hi Istvan,

Thanks you for your thorough research. Did the error also happened with other applications as well? We see it happening with Outlook and last time there was a Font Capture with this error. We suspect it is related to Adobe Acrobat.

Kind regards,

Sean

[Istvan36826407eb7j]

Hi Sean,

No, I didn't see it happening with Outlook or other applications, only with Adobe Reader.

[VTM22995878bha8]

Hi Istvan,

Thanks for the reply.

We see the message with multiple other application. However we suspect Adobe Acrobat plays a big part in the errors. For Outlook for instance there is a add-in. Also it happens when viewing a pdf handler.

At the moment we are testing with two options disabled: Page cache and enhanced security. At first glance we noticed Acrobat starts up faster.

Unfortunately we hear more and more customers complain about issues with Adobe.

[Matt33410725wtgv]

Hi @Serene_nature15C3 any update to this issue?  It's now happening on a lot of my users' machines.

[ttechs6606514]

Hi @amal do you have any news regarding this issue? I have notie the same issue is also happening with our customers accrosss diferent business. 

[S. S]

Hello Everyone, 

We are live with the next release(2024.003.20112).

Please update the app to the latest version and let us know if the issue is fixed.

Thanks,

Souvik

[Miffin]

I had a number of clients experienceing this issue and the update seems to have stopped the error from poping up.
