Answer 1

I had this exact problem and just changed it for myself. That is I navigated to C:/PROGRAM/R and then right clicked on the R to bring up properties. Went to the Security tab clicked on the Group/User that you want to add permissions for. That for me was USER then clicked EDIT and then selected the boxes that were unchecked to Allow control over. I had to do this specifically for each user (of course I was running the entire time as administrator). Clicked Apply/OK and all is well. I can now update/install/ new libraries and what have you for this computer without having to run R as the admin.
