Well, the R code in package tcltk for startup under Windows is, as you could
have found out yourself easily:
.onLoad <- function(lib, pkg)
{
? ?packageStartupMessage("Loading Tcl/Tk interface ...",
? ? ? ? ? ? ? ? ? ? ? ? ?domain = "R-tcltk", appendLF = FALSE)
? ?if(!nzchar(tclbin <- Sys.getenv("MY_TCLTK"))) {
? ? ? ?tclbin <- file.path(R.home(), "Tcl",
? ? ? ? ? ? ? ? ? ? ? ? ? ?if(.Machine$sizeof.pointer == 8) "bin64" else
"bin")
? ? ? ?if(!file.exists(tclbin))
? ? ? ? ? ?stop("Tcl/Tk support files were not installed", call.=FALSE)
? ? ? ?if(.Machine$sizeof.pointer == 8) {
? ? ? ? ? ?lib64 <- gsub("\\", "/", file.path(R.home(), "Tcl", "lib64"),
? ? ? ? ? ? ? ? ? ? ? ? ?fixed=TRUE)
? ? ? ? ? ?Sys.setenv(TCLLIBPATH = lib64)
? ? ? ?}
? ?}
? ?library.dynam("tcltk", pkg, lib, DLLpath = tclbin)
? ?.C("tcltk_start", PACKAGE="tcltk")
? ?addTclPath(system.file("exec", package = "tcltk"))
? ?packageStartupMessage(" ", "done", domain = "R-tcltk")
? ?invisible()
}
This tells us that if you do not have "MY_TCLTK" defined on startup of R,
you probably forgot to select the tcltk files for 64 bit from the installer
when installing your version of R.

I agree that this is a really outdated source but I did not find the
way to tell R using correctly the tcl version included (at least for
the 64 bit version).
If I remove the environment variables, things work for R 32 bit (it
uses the tcl version included), but it does not work in R 64 bit.
Where are the configuration files used to define the path to each tcl
version ?

Don't read outdated sources but the manuals.
The R binary distribution comes with tcltk under Windows (in
${R_HOME}/tcl)
for both 32-bit and 64-bit and will user a different tcl if you set
environment variables.
Hence the easiest thing is just to tell R not to use your otehrwise set
environment variabes and use its own tcl version.

But now, it uses only this 64 bit version and thus do not work anymore
in R 32 bit !
In my case, it solves my problem as I will probably use only R 64bit
but I do not like to end with an half solution.

FWIF, tcltk still exists but is now part of the standard R
distribution ("core packages" is the term I think?) and as such is
installed automatically when you install R. Therefore it is not
available from CRAN.
