Cmdstanr error: cc1plus.exe: sorry, unimplemented: 64-bit mode not compiled in

I restarted my computer, removed older cmdstanr installation and installed everything again, and now install_cmdstan gives a few pages of warning messages (pasted a part below), but it does seems to sample.

Thanks a lot !

FWIW, here’s the screenshot of PATH (in case someone has the same problem).
