Hi there,
Thanks for the detailed clarification, that information helps a lot.
What you’re seeing is not an issue with your installation or scanning tool.
Adobe Acrobat includes the Acrobat Reader component internally. During updates or component repairs, Acrobat may refresh or re-register the Reader portion separately. When this happens, inventory or vulnerability scanners can detect it as “Adobe Acrobat Reader” with a different install date, even though it was not installed manually.
Why the install dates don’t match:
Acrobat was clean-installed on Oct 7th. The Reader component gets updated independently as part of Acrobat’s internal update process. There is a possibility that the scan tool is picking up the component update date, not the original Acrobat install date.
Why only 11 out of 28 systems show it:
Those systems likely received a slightly different update path (timing, background repair, user-launched update, or update validation). This does not mean Reader was separately installed or that those systems are misconfigured. Adobe does not install a separate Reader application alongside Acrobat unless explicitly instructed to do so by an administrator. If it's an IT-managed work computer, please try to contact them and see if that helps.
