If you can't update the Adobe Reader program from within the reader (i.e. you have the latest version) then you can ignore the report on the plugin check page. We have seen in the past problems on the plugin check page with detecting the latest Adobe Reader version because Adobe changed the way the AR reports itself.

Adobe doesn't offer the latest version of the Adobe Reader on its downloads page and the only way to be sure that you have the latest AR version is by checking for updates in the AR program until no updates are available.

For what it's worth, the cause of this is the version reported by the nppdf32.dll that ships with Acrobat Reader. I upgraded my Acrobat Reader installation from 15.010.20056.36345 to 15.010.20060. The DLL did not change. I then uninstalled Acrobat Reader and installed version 15.010.20060, after which I checked the version in nppd32.dll -- it was still 15.010.20056.36345.

Thanks..but could you put this in layman's terms..I think you mean that when you install the new version, it comes from adobe or is listed in the registry when you install it as the old version's number for some reason

 I just checked for updates while in the reader program and it said no updates available...have the newest update number installed...I then opened Mozilla Plug in Check and it still shows I have the old version number and that I'm "vulnerable and I need to update"..I checked to see if I have the old version still too and I don't...only the new version is listed in "programs"
