On 9/28/2025 rebooted my Windows 10 PCAnd it implemented the 9/24/2020 Adobe acrobat DC update. Unknown to me at all so activated a Windows 64 version on the same computer using up my second permitted activation. Was the 9/24/2020 a migration by Adobe to make a 64-bit version for Windows? If I want to deactivate one of the two versions on the same computer, do I deactivate the 32-bit assuming I now have a 64-bit version or is this really just the 32-bit version operating under the 64-bit version of Windows 10?
Thanks for your response. Interestingly, I went on the "manage account" drop-down and then clicked on plan details to get back to the image which yesterday showed both a June 28, 2020 32-bit installation and a September 28, 2020 64 bit installation. As you can see from the image below when I went on today, it only shows the 64-bit installation. None of this is the result of any conscious choice on my part but rather merely letting Acrobat Pro DC do whatever it does when it installs itself and doesn't upgrade. When I saw the two installations and read the legend which required that ID activate one of them, that was the genesis of my question. Whether by reason of logging out and logging back in for some intervention on the part of Adobe, thankfully my issue appears to be resolved. [image: image.png]
