Hello,

I need to install Acrobat DC for Desktop 64 bits for Windows 10, I have Acrobat DC 32 bits. I would like to change.

Thanks.

    There are currently installers for Acrobat and Acrobat Reader 64-bit. They can be accessed via https://helpx.adobe.com/acrobat/kb/download-64-bit-installer.html. Note that this not general availability and may not support languages other than English in terms of UI.

     

    Also, this is absolutely not an updater. If you want to install th 64-bit versions, you currently must totally uninstall any 32-bit version. Then you can install the 64-bit version.

     

    Note also that any third party plug-ins (such as PitStop, Quite Imposing, etc.) must be re-installed with 64-bit versions of those plug-ins. Not all plug-in makers have updated their plug-ins to have 64-bit versions.

     

    Finally, be aware that contrary to popular mythology, the 64-bit versions of applications (not just Adobe applications) generally don't provide any higher performance than the 32-bit versions, but rather, provide access to larger memory spaces supporting much larger and more complex documents.

      Hi, I have Adobe Acrobat Pro DC (2019.008.20071) which is 32-bit. 

      I found out that since my Microsoft 365 is 64-bit, I cannot preview PDF files on Outlook or on Windows Explorer unless I change the Acrobat Pro DC to 64-bit. 
      Will I have to purchase it again or can I use the same activation key for a 64-bit?

      Thanks. It is a stand-alone licence 


      Adobe Acrobat Pro DC (2019.008.20071)  is an old version. So if you want to switch to Acrobat Professional have to check wether Adobe still allows you to download such old versions.  

      The closest you can get to buy a stand-alone-edition is to go here and ourchase the Adobe Acrobat Classic with 3 year license (marked with black Acrobat icon):
      https://www.adobe.com/products/catalog.html#category=pdf

      Else Adobe is focusing on leasing. Offering subscription plans, with either monthly or annual payment periods. As Adobe, like many software vendors, have turned from ownership to leasing. 

      To learn about Adobe´s terms for canceling for Adobes subscription plans, see..

      Hi @defaultmy5g6p09tpus ,

       

      I branched your post from an unrelated thread about missing characters.
