I can't delete the required files somewthing about needing permission from TrustedInstaller. For Windows operating system, download the official Uninstaller from Adobe.Make sure that you have closed all browsers, tabs or apps.Double-click on the downloaded Uninstaller.When prompted for confirmation, click on “Yes.”When complete, you will be asked to restart your computer to complete the process.For the last step, press the Windows key and ‘R’ to bring up the ‘Run’ command.In the “open” box, insert C:\Windows\system32\Macromed\Flash and hit “Enter.”This will open the specified folder. Delete all the files in this folder.Repeat the previous three steps, but open the folders and delete the content of:C:\Windows\SysWOW64\Macromed\Flash%appdata%\Adobe\Flash Player%appdata%\Macromedia\Flash Player
