title: Can't upgrade dart sdk
body: <p>I'm using VS Code to practice the Dart language (not flutter, I'm using Android Studio for that). My file's name is main.dart. Anyways, VS Code keeps telling me to upgrade Dart to the latest version.</p>
  <p>Whenever I do, the command prompt/Powershell informs me that access to path 'dart.exe' is denied, specifically C:\tools\dart-sdk\bin\dart.exe.</p>
  <p>How do I fix this?</p>
