Embedded PDF viewing generates error 0:521 and crashes Internet Explorer

[jonathonr21308024]

Hello,

We have at least 3 users that are affected by the issue in the Subject line. All machines are running Windows 10 Enterprise 64-bit with version 19.021.20047 of Adobe Acrobat Reader DC. I've also attached a screenshot of the error message users are receiving. It should be noted that this issue only began occurring after our environment was updated to this version of Reader DC; previous versions did not cause this issue. Is this a new issue in this build? Please advise.

Thanks.

I just updated the affected machines to v19.21.20049. I will let you know what comes up if anything.

We still have one user that's experiences the error message. I ran a repair on the installtion from within Adobe Reader DC and that appears to have cleared it up. I'll post back once I've had the user conduct testing.

We have started seeing this error when opening one pdf to another using links in a browser.  We are running the latest version as of 10/20/2020 it's terribly disruptive to our production environment.  How do we stop this error from occuring?

Im having the same issue.. we have the latest version installed of acrobat dc 21.011.20039 64 bit. it seems to happen when ever we close a pdf and open another right after. I can duplicate this error every time. We are required to use Acrobat DC for our Thompson Reuters File Cabinet software. Our Accountants are like Crack Adicted Hampsters with ADHD and can't wait the 2 or 3 sec it takes DC to shut down before clicking the next link.

Please let me know how to fix this issue.
