Adobe Acrobat Reader DC update

Question

Hi

We have Adobe Acrobat Reader DC version 20.013.20074 installed on our corporate devices by default.

Recently we have seen an auto-update which creates an additioanl entry i.e. Adobe Acrobat DC (64-bit) in Programs & Features - see below:

Can someone please explain what is happening here as it seems to be causing issues such as PDF preview in Windows Explorer and Outlook.

Regards

Not much info here just someone with the same issue: “Yeah, this may be because the latest Reader installs itself as Acrobat DC and not Acrobat Reader DC. We lost PDF file association on our upgraded clients because .PDF is set to be opened by Reader (AcroExch) and now it expects opening by Acrobat DC.”

“Dear user, the fixes for this issue have been applied in the latest release so that Reader will not upgrade from 32 bit to 64 bit machines on Sever OS machines. You can get the latest version of 32-bit Reader from:
https://get.adobe.com/reader/otherversions/

Adobe addressing the fact that they are “silently upgrading” people from 32 to 64 - Acrobat Reader DC migration to 64-bit (adobe.com)

If you have installed the 32-bit Acrobat Reader DC application, you will be automatically upgraded to the 64-bit version of Acrobat Reader DC gradually. This upgrade is silent and currently applicable to a limited number of users. You are excluded from the automatic upgrade to 64-bit if you do any of the following:
- Use an Enterprise or Federated ID to sign in to Acrobat Reader DC.
- Customize Acrobat Reader DC using the Acrobat Customization Wizard and install it.
- Install third-party plugins.
- Disable the automatic updates in Acrobat Reader DC.
