DRA requires 32 bit to installed. Adobe Reader DC has released a 64 bit version and is auto updating 32 bit to 64 bit as of Nov 4 2021. This makes updating to a new version of DRA even that more annoying. As it requires you to uninstall 64bit and re-install 32 bit.

Please make DRA compatible with 64 bit, if not already and modify the check done by the installer.
