안녕하세요. 엔지엠소프트웨어입니다. 플러터를 설치하려고하니~ "Windows Version (Unable to confirm if installed Windows version is 10 or greater)"와 같은 에러가 발생하는군요. 어떤 이유인지는 모르겠지만, stable에서는 윈도우 버전을 확인할 수 없었습니다. 그래서, master로 변경해야 하는데요. 아래와 같이 플러터 채널을 확인 해볼 수 있어요.

C:\Users\ngmas>flutter channel
Flutter channels:
  master
  main
  beta
* stable

채널을 마스터로 변경 해봅시다.

C:\Users\ngmas>flutter channel master
Switching to flutter channel 'master'...
git: branch 'master' set up to track 'origin/master'.
git: Switched to a new branch 'master'
Successfully switched to flutter channel 'master'.
To ensure that you're on the latest build from this channel, run 'flutter upgrade'

채널 변경을 완료하려면 flutter upgrade를 실행해야 한다는군요.

flutter doctor를 다시 실행 해보세요. 에러가 사라진걸 확인할 수 있습니다.
