On a AWS EC2 Windows 2012 server, my goal was to write some data to S3 bucket. I was using a small Powershell Script to copy the file to the S3 bucket. For that I needed to Install AWS Tools for Powershell and I used following command at Powershell prompt running as administrator:

Windows PowerShell

PS C:\\Users\\SRV> Install-Module -Scope CurrentUser -Name AWSPowerShell.NetCore -Force

and it failed with following error:

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\\SRV\\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?

PackageManagement\\Install-PackageProvider : No match was found for the specified search criteria for the provider

'NuGet'. The package provider requires 'PackageManagement' and 'Provider' tags. Please check if the specified package

has the tags.

Solution:

The solution is to enable TLS 1.2 on this Windows host, which you can do by running Powershell in administrator mode:

Set-ItemProperty -Path 'HKLM:\\SOFTWARE\\Wow6432Node\\Microsoft\\.NetFramework\\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord

Close your Powershell window, and reopen as administrator and check if TLS protocol is present by typing following command on PS prompt:

[Net.ServicePointManager]::SecurityProtocol

If the above shows Tls12 in the output, then we are all good and now you should be able to install AWS Tools.

I hope that helps.
