The Windows OS has been reducing the users' privileges progressively and increasing the authority of built-in features with each version to protect better-said users from threatening applications and threats. As a result, some applications that the users may find useful may be blocked from being installed by one of the defensive Windows features. In that case, the 'An administrator has blocked you from running this app' warning message will appear. Another description for the same event is 'This app has been blocked for your protection.' warning message.
To bypass the cause of this problem and finally install the desired program, users will have to tinker a bit deeper with Windows OS. The method that seems to have the best chance of success is to open the setup file of the program that is being blocked in an elevated Command Prompt and run it from there. To do so, type 'command prompt' in Search, right-click the result that appears and select 'Run as administrator.' Now that an elevated Command Prompt has been established, you have to enter the exact location of the app's file. To get the price location path, right-click the installation file, select 'Properties,' and copy the path written in the 'Location' field. Enter the location in Command Prompt and add the exact name of the file itself at the end. Pressing Enter should override the built-in Windows features and initiate the installation of the program.
