Erreur lors du lancement de l'installateur

Prada97 -  
Hello, when I download software it works one time out of two. Most of the time a message appears: "ERROR LAUNCHING INSTALLER". I can't take it anymore, I can barely download anything even the most basic software like VLC media player! I read somewhere that I should rename the software or change its folder but that still doesn't work...
Please if you have a solution, take the time to respond..

A desperate computer user...

    "Even the most basic software like VLC": I hope at least you're downloading from official sources (http://www.videolan.org/vlc/ for VLC).

    "ERROR LAUNCHING INSTALLER": this seems to be a corruption of Windows installer.
    If the first "solution", downloading from the right place and not from installers stuffed with ads and adware, doesn't work, open a console by:
    - On Windows Vista/7/8, searching for "cmd", then right-clicking -> open as administrator
    - On Windows XP, pressing Windows + R, typing "cmd" in the window then hitting enter
    A black window will appear. Enter the text "sfc /scannow", press enter and wait.

      Thank you very much for your response, but when I type sfc /scannow it says: "To use the sfc utility, you must be a user running a control session." What should I do?

      I said to search for "cmd" in the start menu, then right-click on "cmd.exe" -> run as administrator.
      If you're on Windows 8, I think searching for "Command Prompt" in the settings should be enough (you need to click on it to launch it, of course).

      Thank you, it worked, but it didn't solve my problem at all. It still persists... Thank you anyway :)
