Unable to install Plesk on Windows: The password does not meet password policy requirements

Symptoms

• The following error occurs in an attempt to install Plesk on Windows:
  

  CONFIG_TEXT: [2018-03-05 23:37:30.174889] MSI (04): Critical action 'Saving administrator password...' failed: Command "C:\Program Files (x86)\Plesk\bin\admin.exe" --set-admin-password * failed with code 1. Output: Validation failed. The password does not meet password policy requirements because it is not complex enough. The password must contain at least 6 characters, and it must include characters from three of the following four categories: uppercase letters, lowercase letters, numbers, and non-alphanumeric characters.
