Error installing greek inputenc

I’m trying to use Greek text with babel package. When trying to install it, a message pops up: "Unfortunately, the package greek-inputenc could not be installed. Please check the log file: C:UsersfederAppDataLocalMiKTeXmiktexlogpdflatex.log". How can I fix this? Screenshot attached. Notice that I use RequirePackage because the file is a .sty.
