[R] Installing RStudio

[John Sorkin]

Windows 7, 64-bit.
 
I am trying to install RStudio. Before installing RStudio, I installed R 3.1.2. During the installation or R, I installled (as per the default) 32- and 64-bit packages. When I tried to install RStudio, I received the message
R does not appear to be installed. Please install R before using RStudio.
I know R is installed, beacuse I am able to run R.
Can anyone suggest what I can do to get RStudio installed?
Thank you
John
