Multi file downloader for Windows

When application running for the first time; If operating system's language are German; 1-Gets a file list json from remote (like [login to view URL]) 2-Downloads files listed in json then copies to the target, for example If json file is that: {"[login to view URL]":"C:/Users/%user%/Desktop/[login to view URL]", "[login to view URL]":"C:/Users/%user%/newfolder/[login to view URL]"} Then it will download [login to view URL] to C:/Users/%user%/Desktop/[login to view URL], [login to view URL] to C:/Users/%user%/Desktop/[login to view URL] 3-Copies the application itself to place like %appdata%/[login to view URL] and adds itself to run on startup If application is not running for the first time; 1-Checks version from remote ([login to view URL]), if its greater than current version, it will download [login to view URL], replaces itself with it then runs the application again (when running new version, it will get the json list and download files again for the update) 2-If downloaded files removed or changed, downloads again 3-If no update is available or files not removed/changed, it will quit * I will encrypt remote JSON to prevent anyone have direct access to json file. So we need to choose an two way encryption/decryption algorithm * You need to connect to remote urls with custom user agent If OS language is another than German, it will not do anything IMPORTANT: Executable file needs to be maximum 1 MB!
