title: How do I correctly install the PowerShell MSOnline module in Windows 8.1 Enterprise?
body: <p>I'm trying to write some scripts for Azure Active Directory / Office online, and I'm completely unable to install the MSOnline powershell module. I've installed the Office Sign In Assistant version 7.2 (64-bit for my 64-bit machine). When I try to run the MSI installer for the PowerShell module, it says it can't find the sign in assistant. When I install the powershell module through PowerShellGet, and then run the commands, it fails with:</p>
  
  <p>Connect-MsolService : The Microsoft Online Services Module is not configured properly. Please uninstall and then reinstall the module.

  <p>Is there any way to get this installed ? I've even changed the language of my system to US-English and installed the correct language pack (because I've run into issues before with things not installing correctly if the system language is not US English)</p>
