Can't install on Win7

Just went to try the scoop installer after installing powershell 3.0 on Win7

Install .NET Framework 4.5 or above then try again.

Is 4.5+ always required? If so, we should update the docs.

[chawyehsu]

@rasa Yes, Tls12 needs .NET 4.5 at least.

Should I add a check for Tls12 to bin\install.ps1?

if([System.Enum]::GetNames([System.Net.SecurityProtocolType]) -notcontains 'Tls12') {
    Write-Output "Scoop requires at least .NET Framework 4.5 to support TLS1.2 connections."
    Write-Output "Please download and install it first:"
    Write-Output "https://docs.microsoft.com/en-us/dotnet/framework/install/index"
    break
}
