Install fails with provided instructions

On both a work and home machine, when trying to install the module it fails, and given the alias it is failing on, I'm not sure if I want to force it:

NuGet provider is required to continue
PowerShellGet requires NuGet provider version '2.8.5.201' or newer to interact with NuGet-based repositories. The NuGet
 provider must be available in 'C:\Program Files\PackageManagement\ProviderAssemblies' or 'C:\Users\Brendan
Grant\AppData\Local\PackageManagement\ProviderAssemblies'. You can also install the NuGet provider by running
'Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force'. Do you want PowerShellGet to install and import
 the NuGet provider now?

Both machines are running Windows 10 Professional, System.Environment]::OSVersion.Version.ToString() is: 10.0.15063.0 and $PSVersionTable reports:


PSEdition                      Desktop
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0...}

The other PC notes that PSVersion BuildVersion are 5.1.15063.674

Time permitting, I'll try from source a bit later.
