Try to run stan model:

```
example(stan_model, package = "rstan", run.dontrun = TRUE)

```

and getting the error message:

```

Seems like my question relates to installation so there is following information:

- Operating System: Windows 10 Enterprise, 64-bit OS, x64-based processor
- RStan Version: 2.21.2
- Output of `writeLines(readLines(file.path(Sys.getenv("HOME"), ".R/Makevars")))` - n/a
- Output of `devtools::session_info("rstan")`:

I had a look at the other similar posts, but they have not worked for me. Any advise would be most appreciated.

Hi Namaruva,

You just need to reinstall `rstan` and `StanHeaders` from source. Try restarting R (making sure that `rstan` doesn’t get loaded) and run:

```r
# Compile packages using all cores
Sys.setenv(MAKEFLAGS = paste0("-j",parallel::detectCores()))

remove.packages(c("StanHeaders","rstan"))
install.packages(c("StanHeaders","rstan"),type="source")

```

Thanks [@andrjohns](https://github.com/andrjohns)!  
Actually, the problem was fixed via an approach from your post from [here](https://discourse.mc-stan.org/t/modeling-failed-warnings-c-users-r-34-1-3-rtools40-usr-mingw-bin-g-not-found-errors-multiple-results-for-cxx14flags-found-something-is-wrong-false/19154/54).  
Thanks again for your help!
