**Describe the bug**
Installing CmdStan from CmdStanR 0.5.2 with R4.2 on Window… s 11 fails.
**To Reproduce**
Create a new project and run:
```
cmdstanr::check_cmdstan_toolchain(fix = TRUE)
cmdstanr::install_cmdstan()
```
Console output in R Studio:
```
The C++ toolchain required for CmdStan is setup properly!
* Latest CmdStan release is v2.29.2
* Installing CmdStan v2.29.2 in E:/Documents/.cmdstan/cmdstan-2.29.2
* Downloading cmdstan-2.29.2.tar.gz from GitHub...
* Download complete
* Unpacking archive...
Warning: cannot open file 'E:/Documents/.cmdstan/cmdstan-2.29.2/make/local': No such file or directory
```
If I look at the directory structure of the unpacked archive (from the install attempt), the issue seems to be that 'cmdstan-2.29.2' is repeated twice in the path: the content of CmdStan is located at ‘E:/Documents/.cmdstan/cmdstan-2.29.2/cmdstan-2.29.2/’, which would explain why the make/local is not found since it assumes 'cmdstan-2.29.2' only exists once in the path.
**Operating system**
Windows 11
**CmdStanR version number**
0.5.2
**Additional context**
I do not think this issue is W11 specific since I always had issues installing CmdStan using CmdStanR (even when still on W10). Not sure it was exactly the same issue I had back then though, but I think it was.
