I just encountered something that looks exactly like that with R
4.0.0 and the latest RStudio AND with Rtools40 installed under Windows
10 (AND some manual adjustment of the path to delete references to old
versions of Rtools and make sure Rtools40 was there).
I got around it by have Rtools40 installed AND running
"install.packages('xmlw')" inside R 4.0.0 inside a CMD prompt. That
worked, even though the same command inside RStudio failed with:
WARNING: Rtools is required to build an R package but no version of
Rtools compatible with the currently running version of R was found.
Note that the following incompatible version(s) of Rtools were found:
- Rtools 3.5 (installed at C:\Rtools).
I got this message after deleting references to C:\Rtools from
the path and rebooting.
*** I BELIEVE YOU NEED Rtools40 installed, because binaries for some
packages are not (yet) available for R 4.0.0.
Hope this helps.

Wouldn't packages that have to be built from source on installation
require Rtools?

Thanks to all - very helpful. I search from c:\ and now find file
.Renviron located in C:\Users\USER\Documents. That does it.
I would like to pose an additional question, since it would also fall
under the same subject line. This is an RStudio question but since I am
using the free version the RStudio folks would not help me.
My students simply need to install packages and are not building any
packages so they have no reason to install Rtools.
When they install (not build) packages (from CRAN or file archive) they
received the same warning message saying
"Rtools required to build a package".
This is nonsense of course as they are, as I said, simply installing. I
tell them to user an older RStudio version, specifically 1.1.463 that's
free of that warning. Any idea?

Dear Steven,
It's possible that Windows will hide .Renviron, but it's generally a good idea, in my opinion, in
Folder Options > View to click "Show hidden files" and uncheck "hide
extensions". Then .Renviron should show up (once you've created it).
Best,
John

Thanks John. Where is file .Renviron located? It must be a hidden file.
I cannot find it.

Dear Steven,
Did you follow the instruction on the Rtools webpage to add
PATH="${RTOOLS40_HOME}\usr\bin;${PATH}"
to your .Renviron file?
I hope this helps,
John

Dear All
I updated to R-4.0.0. and also installed the latest Rtools 4.0 (to
now the new default folder c:\rtools40). While compiling a package
(binary) I received the follow marning message saying Rtools is
required. Any clues? Thanks.
