title: Cannot install latest Azure PowerShell
body: <p>I am trying to install the latest Azure PowerShell (released Nov. 9th 2015). If I try to install it using Web Platform Installer, I get the following error:</p>
  
  <blockquote>
    <p>Azure Modules from the PowerShell Gallery are installed on this machine.  Please remove these modules before installing this MSI.</p>
  </blockquote>
  
  <p>If I run <code>Get-InstalledModule</code> in PowerShell, I see that the Module <code>Azure</code> (version 0.9.11) is installed. So I tried uninstalling it using the PowerShell command <code>Uninstall-Module Azure</code>. Here I get the following error:</p>
  
  <pre><code>PackageManagement\Uninstall-Package : The property 'ModuleBase' cannot be found on this object. Verify that the
  property exists.
