Error installing Rtools - devtools::has_devel() fails

Question

I want to create an R package and downloaded Rtools and packages c("devtools", "roxygen2", "testthat", "knitr"). Now I check if everything is alright:

library(devtools) has_devel()

and it's not, I get the error:

"C:/Users/xxx/DOCUME~1/R/R-33~1.1/bin/x64/R" --no-site-file --no-environ --no-save --no-restore  \
  --quiet CMD SHLIB foo.c 

Warning message:
running command 'make -f "C:/Users/XYZ/DOCUME~1/R/R-33~1.1/etc/x64/Makeconf" -f "C:/Users/XYZ/DOCUME~1/R/R-33~1.1/share/make/winshlib.mk" SHLIB="foo.dll" WIN=64 TCLBIN=64 OBJECTS="foo.o"' had status 127 
Error: Command failed (1)

I use Windows and the freshest RStudio.

Do you know what it means or how to repair it?

lol I have just ran this code:

install.packages("devtools")
library(devtools)
install_github("hadley/devtools")
devtools::build_github_devtools()
find_rtools()
has_devel()
build_github_devtools()

from https://github.com/hadley/devtools/issues/1219

and now has_devel returns TRUE :O :D

Not sure if this would work for you, in a previous time I changed the R executable to run as administrator. (don't do that!) I went to C:\Program Files\R\R-3.4.1\bin\x64 and right clicked the R executable. go to compatability mode, deselect run as administrator.

Everything works again.
