I am running R 4.2.2 on a Windows 11 Machine. I am trying to follow along with the cmdstanr and cmdstan installation instructions but can’t seem to get cmdstan to install.
I successfully installed cmdstanr into my renv project environment. Now, according to the documentation, I need to install cmdstan.
When I do so, I recieve the following error:
> install_cmdstan( cores = 4, overwrite = T)
The C++ toolchain required for CmdStan is setup properly!

I have RTools42 installed and have gone to my control panel to set my system path variable to include: C:\rtools42\usr\bin and C:\rtools42\mingw64\bin as discussed here. I also tried running an example model as suggested here, but recieve the following error:
> fit <- cmdstanr_example("logistic")

I’ve also checked out this blog post that folks seem to reference, but still can’t seem to get things to work.
This has been challenging me all morning…
