The Problem:

Node.js installation failed due to errors with codes 2502 and 2503. “The installer has encountered an unexpected error installing this package. This may indicate a problem with the package.”

  2. Click on the “File” menu and “Run new task“.
  3. Click “Browse” and choose the msi installer file.
  4. Check “create this task with administrative privileges“.
