Windows PowerShell script fails to run and reporting error... "cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about signing".
You are getting this error because the security settings built into Windows PowerShell include something called the "execution policy".
Release: DSWAHA01300-12-Workload Automation DE-High Availability
The execution policy determines how (or if) PowerShell runs scripts. By default, PowerShell execution policy is set to Restricted; that means that scripts including those you write yourself would not run.
For example, PowerShell 1.0 installs to the directory;
%SystemRoot%\system32\windowspowershell\v1.0 - for 32-bit version, and to
%SystemRoot%\system64\windowspowershell\v1.0 - for 64-bit version.
If you are running on a 64-bit operating system, there is a 32-bit version of PowerShell and a 64-bit version of PowerShell.
The script packager is a 32-bit program, so it uses the 32-bit version of PowerShell. When you launch the script directly from PowerShell, it uses the 64-bit version of PowerShell.
Make sure both versions have the correct execution policy.
