    Acrobat Runs Slow/Not-Responding

    Trav2016 Level 1

      My company recent upgraded from Adobe Acrobat Pro 11 to Adobe Acrobat DC. We had to upgrade due to licensing and support ending for that product.


      After upgrading Acrobat we have noticed when using Adobe ie: Opening/scrolling/etc the program runs slower. A normal PDF document will have about 40 Pages. Another thing we noticed is when you print from Microsoft Excel to Adobe PDF, we notice Excel will lock up and not respond. After about 30sh seconds, you will be able to see the Adobe PDF printer dialog box. After you save the document, Excel will then respond. The normal amount of pages we print from Excel is 6 Excel sheets.


      What I was wondering is what I can do to improve the performance of Adobe PDF documents when you have them open and scrolling through/zoom in or out/etc. Along with what I can do to improve the performance when someone prints from an Excel document to an PDF document.


      Thank you for you Advice!

          Hi Trav2016,


          As per the issue description mentioned above, Acrobat DC is running slow also printing takes time when printing to Adobe PDF printer in excel, is that correct?


          Could you try following steps:

          1- Reboot the machine once if you haven't already and check.

          2- Check if an update is available for Acrobat using "Check for updates" option under "Help" menu, reboot the machine after installing update and try again. You may also download updates from here: Adobe software and product updates

          3- If that doesn't work, try resetting preferences for Acrobat using the steps given in this link: How to reset Acrobat Preference settings to default. , reboot the machine after resetting preferences and check.


          Also, let us know dot version of Acrobat and the operating system installed on the machine? You may refer to the steps given in this link on how to check the version: Identify the product and its version for Acrobat and Reader DC


          Let us know if you need any help.

            I know my response is a little late to the game, but I haven't found my solution suggested anywhere and thought I would share it, although it probably will affect a small number of people.


            In my case Acrobat Pro would not access my menu items or scroll without the spinning beachball, sometimes lasting for more than 10 seconds. This was making the program unusable. After removing preference files to no affect, it occurred to me that my virus scanner (Intego VirusBarrier) was set to Real-Time scanning. Once I turned it off, the program was back up to speed. As I can designate VirusBarrier to skip certain folders or files I can still leave it on for downloads with turning it off and on. I don't know if other virus programs will cause the same issue, but it is something to consider if you use one that scans files as they are opened.


            iMac OS X 10.14.1

            Intego VirusBarrier 10.9.16

                I think Adobe needs to work on re-writing some of its software. Especially the part that deals with the Anti-Virus. I just checked, our Windows 10 workstations that are experiencing this issue all run the same hardware, same OS, and same anti-virus. PLUS, the real-time protection is enabled (aka Advanced Active Protection).


                On my Anti-Virus, I can set it to scan real-time, and any time a file-extension that I set is run.


                I'm using VIPRE Endpoint Security.
