Every time I open VS to work I get a notification saying that I have to install an update. I click on it, I try to install the update, the installer downloads, but when it has to install gives an error saying that: "another program is blocking the folder C:\Program Files (x86)\Microsoft Visual Studio\Installer or a file inside it. Close the applications that could be using it and try again." But I'm not running any other program that could be using it. I tried reestarting the pc, but no way. I also tried to repair and Uninstall VS but since I have to update it doesn't let me access to the VS installer either.
