Error Code from a Client

Hello,

I am not at all familiar with RStduio, I am just reaching out on behalf of a client I deal with who has it on their computer.

They are running the command "install.packages("psych")" and getting an error code.

Error Code is:
This is the error:

install.packages("psych")
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

The downloaded source packages are in

I was just wondering if you had any fixes for this/steps of what to do.

I also downloaded Rtools from https :// cran.r-project.org/bin/windows/Rtools/history.html but I still get the same error.

You are missing the mnormt package for psych to work but it requires R >= 4.0.0 so you have to update R first in order to install it.
