The "AdbeRdr" naming pattern has been in use for many versions, from Adobe Reader 9 to the final releases of the XI series. It's important to note that the version for the English language. For other languages, the file would be named similarly, such as AdbeRdr11010_de_DE.exe for German. A complete list of available installers for this update was provided by Adobe in its official release notes.
Adobe officially ended support for years ago. This means that while the software might still technically "work" on your computer, it no longer receives: adberdr11010-en-us.exe
