New R-version installed - RDCOMClient not supported?

Question

Installed newer R-version 4.3.2, but now I can't install RDCOMClient-package:

install.packages("RDCOMClient")
Warning in install.packages :
  package ‘RDCOMClient’ is not available for this version of R

A version of this package for your version of R might be available elsewhere,
see the ideas at
https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages
> 

Is there any way to request an update from the creators? Another source?

As a last resort, is there a substitute? Thanks!

UPDT1: Didn't know that, or had forgotten, in any ways - I get this error:

install.packages("RDCOMClient", repos = "http://www.omegahat.net/R", type = "win.binary")
Warning in install.packages :
  unable to access index for repository http://www.omegahat.net/R/bin/windows/contrib/4.3:
  cannot open URL 'http://www.omegahat.net/R/bin/windows/contrib/4.3/PACKAGES'

   package ‘RDCOMClient’ is available as a source package but not as a binary

Trying installation from github, as suggested from the other thread, also does not work for me:

UPDT2: Running devtools::find_rtools() or devtools::find_rtools(4.3) both return [1] TRUE and Found in Rtools 4.3 installation folder [1] TRUE - so check on that I presume.

I assume you meant that td <- tempfile() should be tf <- tempfile()? If so running the entrie thing sadly does not work:

tf <- tempfile()
> dir.create(tf)
> withr::with_libpaths(new=tf,devtools::install_github("omegahat/RDCOMClient"))
