Error Updating Seurat Windows

[olaf-c]

> install.packages('Seurat')
leads to the following error:

Error: Error installing package 'SeuratObject':
========================================

* installing *source* package 'SeuratObject' ...
** package 'SeuratObject' successfully unpacked and MD5 sums checked
** using staged installation
** libs
Error in system(paste(MAKE, p1(paste("-f", shQuote(makefiles))), "compilers"),  : 
  'make' not found

I have reinstalled RTools. Changed the path. Updated the Renv files.
make is recognized in terminal. It only seems to be the Seurat installation that is breaking. All other libraries are updating without fault.

I have attempted to also update Seurat using GitHub.
> remotes::install_github("satijalab/seurat", "seurat5", quiet = TRUE)
This led to the following error:

Error: Failed to install 'Seurat' from GitHub:
  Could not find tools necessary to compile a package
Call `pkgbuild::check_build_tools(debug = TRUE)` to diagnose the problem.
In addition: Warning messages:

2: In untar2(tarfile, files, list, exdir, restore_times) :

However, > pkgbuild::check_build_tools(debug = TRUE) created the following output:
