unable to install package in R Studio because file is not writeable

Question

I am facing a problem while trying to install packages in Rstudio.

For example, I face this error when I try to install devtools:

> install.packages("devtools")

  'lib = "C:/Program Files/R/R-4.0.3/library"' is not writable
Error in install.packages : unable to install packages 

Any suggestions about what should I do?
