readonly option is set add to ! override - Windows 8.1

Question

I was trying to change the colorscheme in vimrc. But, when I try to say, I get the following error readonly option is set add to ! override, provided that I'm using Windows 8.1. How can I fix this error?

Thanks.

You need to open vimrc with write permission. In windows it probably would mean opening it as admin.
Also try to do what this message suggests - :w! instead of :w
