The current version of Adobe Acrobat Reader for Windows is 21.005.20048, released on 08/06/2021is directed to Windows 11. This is an update that fixes critical flaws of the previous version 21.001.20155 released on 11/05/2021. The previous updates are important since they sign the disappearance of Flash, which has become obsolete.
As a result, various Flash-dependent tools and options are no longer available or have been replaced. This is the case for example of the functions “Update”, “Filter”, “Export” (All/Selected), “Archive” “Add” and “Delete” response form files. The ability to embed Flash content has also been removed from the menu of PDF Maker, the extension for Microsoft Word and Excel.
