Im on windows 10 so i cant say for certain. but im not having issues. and using choosenim am getting the pre-compiled version.
I installed choosenim by getting the zip, extracting it, and running the runme.bar file without adming mode. then, open powershell and run $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User") Run to refresh your path then, simply `choosenim stable` and it will download nim 1.6 using binaries I had to run `choosenim update stable` instead because i already had nim 1.4 installed.
