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I agree that this is a really outdated source but I did not find the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 ?

I achieve to make tcltk work on R 64 installing Active tcltk8.5 64bit

Don't read outdated sources but the manuals.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.

Taking a quick look for it, it seems that they have replaced it with
tcltk2. I just did the installation with the same version in windows
and it auto loaded the tcltk package and I never installed that
package to begin with. I would try it with tcltk2 and see if you get
the package to install appropriately. I'm not sure why tcltk isn't on
CRAN anymore, it makes no sense not to have both tcltk and tcltk2, but
here's hoping this helps you out.

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.
