Are you using R 4.0 or R 3.6?

I installed R 4.0 (previously using 3.6) which combined with Rtools40 managed to get Rstan installed.

HI.
I am also facing same issue. Please help

Can you post the full error message that you’re getting?

After searching a lot solutions, finally I delete .Renviron file in C:\Users\My name\Documents. Then rtools40 works.
