523:523 Error update to 2019.021.20048

Our users' Acrobat Reader DC clients updated to 20048 this morning and now are unable to preview pdf's directly via Internet Explorer. Changing the default pdf viewer does not impact this due to specific relations between Acrobat and IE from what I can tell and the prompt to download a pdf before viewing it is skipped altogether. We have confirmed that this is in relation to Trend Micro Apex One blocking it. This doesn't seem to occur in other browsers from what we can tell but unfortunately some of our business systems are still only compatible with Internet Explorer. We are EXTREMELY hesitant to whitelist the Acrobat exectuables due to PDF's being such a common vector for Malware/Trojans. We get dozens of detections from files opened by Acrobat daily and needless to say it's not an option. For the time being our users are making due with the complete removal of Acrobat Reader but hopefully this is addressed by either Adobe or Trend Micro. I've posted with Trend Micro in a related support case as well.

    Hi Jasong,

     

    We're sorry for the trouble you had, would it be possible to disable the Trend Micro solution and check the behavior.

     

    Also, whitelist the Acrobat.exe and AcroRd32.exe in Trend Micro to the Trusted Programs List and check.

    reference location:

    C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcrRD32.exe and C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\Acrobat.exe

     

    Let us know how it goes and share your observations.

     

    Thanks,

    Anand Sri.

    Hi Anand,

     

    Also facing the same issue, un-checking Enchanced Security resolves the issue.

     

    However, this is againt our policy and do not like having this un-checked.

     

    I may have got it down to EULA not being agreed, or similiar issue, where updating manually brings the agreement up, however it seems most may have had auto-update and caused this issue.

     

    Is there a way for the agreement to be accepted manually without going into registy, doesn't seem to work. 

     

    Pending to reinstall AcroRdrDCUpd1902120048.msp to see if that helps.
