adobe 32bit updating automatically to 64bit

We are in medical and use adobe reader 32bit, and it hast to be 32bit for the majority of our software. We are seeing several machines automatically updating to 64bit which is incompatible with our software.

 

I see multiple threads regarding this but all are using hard blocks on updates. We need to support security updates and stop the auto update to 64bit at the same time, we cannot just block all updates via registry.

 

What can we do to maintain just the 32bit version?

    Correct answer ravinderg62643219

    Is the key "bUpdateToSingleApp" a new key? I am unable to locate the support documentation and my understand is that the only key supported here is just "bUpdate".

    https://www.adobe.com/devnet-docs/acrobatetk/tools/PrefRef/Windows/Updater-Win.html#idkeyname_1_28262

     

    What about the key Mode? If we were to create "bUpdateToSingleApp" will mode continue to update to 64bit automatically or will it now update only 32bit updates?

     

    Additionally it was reported in the thread you have linked that the "bUpdateToSingleApp" key ravi mentioned did not work for that user.


    Hi,

    Yes, this is a new key  introduced. Please try the following stpes 

    1. Uninstall 64-bit Reader installed on the machine.

    2. Restart the machine (optional step)

    3. Create the key to block the upgrade

    • [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown]
      "bUpdateToSingleApp"=dword:00000000
      [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown]
      "bUpdateToSingleApp"=dword:00000000

    4. Install 32-bit Reader from https://get.adobe.com/reader/otherversions/ 

    • select OS  & langage from drop down
    • select 32-bit Reader from drop down and then install 32-bit Reader.

    I truly wondering who's the geniuses behind this extremely intrusive update! What sort of value added thing that can be achieved by forcing update without user consent? Think producttive function guys, don't add unneccessary work to other people for your own work benefits!

      Hi there 

       

      Hope you are doing well and sorry for the trouble. As described the Adobe reader 32 bit is automatically updating to 64 bit.

       

      Please check out the suggestion provided in the similar discussion https://community.adobe.com/t5/acrobat-reader-discussions/how-can-i-make-32-bit-reader-update-to-only-32-bit-not-64-bit/td-p/12376081#M83496 and see if that works for you too.

       

      Regards

      This is not going to work for us for more than a week or two. We need to be able to update adobe but still maintain the 32bit version. The solution you linked stops all updates for adobe, and that would leave us wide open without updates.

        Hi @defaults3f3n9vkgnu3 

        Please use the solution described by @Ravi Gour  in the https://community.adobe.com/t5/acrobat-reader-discussions/adobe-reader-changing-itself-to-64bit-when-we-need-32bit-for-the-preview-handler-in-outlook/m-p/12397088#M83425 thread.

        Solution is:

        To revert back to 32-bit version of Reader, please uninstall 64-bit Reader, install 32-bit Reader from https://get.adobe.com/reader/otherversions/ (select 32-bit version to download from dropdown).

        Create following registry key to block automatic upgrade

        Key: bUpdateToSingleApp , Value = 0 , type = dword

        Location : HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown
