Have you unblocked each PS1 file as described in the Quick Start section?
Check your system for requirements:
- Does the system have SQL Server 2008 or above?
- Is the sp_configure setting xp_cmdshell enabled?
- Is your PowerShell version 3.0 or above? Check your Powershell version by running $PSVersionTable.PSVersion in a Powershell window. You should have a “Major” number of 3 (Powershell 3.0) or higher. Otherwise, the installer will not work.
- Is the PowerShell execution policy set to RemoteSigned?
