Unable to install packages

When I try to install a package, I get this error. I have already tried to change the mirror and unselect "Use Internet Explorer library/proxy for HTTP", It didnt help at all. Can someone tell me what to do?

install.packages("GGally")

The report mentions R 3.3.1 on Windows and failures from install.packages() when accessing the listed CRAN mirrors. No repository files, tests, or implementation entry point are identified; first determine whether this is a packrat problem or an external R/network configuration issue, then establish a reproducible failure and a defined fix before changing code.
