Function Save-VcRedist { <# .SYNOPSIS Downloads the Visual C++ Redistributables from an manifest returned by Get-VcList. .DESCRIPTION Downloads the Visual C++ Redistributables from an manifest returned by Get-VcList into a folder structure that represents release, version and processor architecture. If the redistributable exists in the specified path, it will not be re-downloaded. For example, the following folder structure will be created when downloading the 2010, 2012, 2013 and 2019 Redistributables to C:\VcRedist: C:\VcRedist\2010\10.0.40219.325\x64 C:\VcRedist\2010\10.0.40219.325\x86 C:\VcRedist\2012\11.0.61030.0\x64 C:\VcRedist\2012\11.0.61030.0\x86 C:\VcRedist\2013\12.0.40664.0\x64 C:\VcRedist\2013\12.0.40664.0\x86 C:\VcRedist\2019\14.28.29913.0\x64 C:\VcRedist\2019\14.28.29913.0\x86 .NOTES Author: Aaron Parker Twitter: @stealthpuppy .LINK https://stealthpuppy.com/VcRedist/save-vcredist.html .PARAMETER VcList Specifies the array that lists the Visual C++ Redistributables to download .PARAMETER Path Specify a target folder to download the Redistributables to, otherwise use the current folder. .PARAMETER Proxy Specifies a proxy server for the request, rather than connecting directly to the internet resource. Enter the URI of a network proxy server. .PARAMETER ProxyCredential Specifies a user account that has permission to use the proxy server that is specified by the Proxy parameter. The default is the current user. .PARAMETER NoProgress Specify this switch with -Verbose to show verbose output but also suppress Invoke-WebRequest progress to speed downloads. .EXAMPLE Save-VcRedist -VcList (Get-VcList) -Path C:\Redist Description: Downloads the supported Visual C++ Redistributables to C:\Redist. .EXAMPLE Get-VcList | Save-VcRedist -Path C:\Redist Description: Passes the list of supported Visual C++ Redistributables to Save-VcRedist and downloads the Redistributables to C:\Redist. .EXAMPLE $VcList = Get-VcList -Release 2013, 2019 -Architecture x86 Save-VcRedist -VcList $VcList -Path C:\Redist Description: Passes the list of 2013 and 2019 x86 supported Visual C++ Redistributables to Save-VcRedist and downloads the Redistributables to C:\Redist. .EXAMPLE Save-VcRedist -VcList (Get-VcList -Release 2010, 2012, 2013, 2019) -Path C:\Redist Description: Downloads the 2010, 2012, 2013, and 2019 Visual C++ Redistributables to C:\Redist. .EXAMPLE Save-VcRedist -VcList (Get-VcList -Release 2010, 2012, 2013, 2019) -Path C:\Redist -Proxy proxy.domain.local Description: Downloads the 2010, 2012, 2013, and 2019 Visual C++ Redistributables to C:\Redist using the proxy server 'proxy.domain.local' #> [Alias("Get-VcRedist")] [CmdletBinding(SupportsShouldProcess = $True, HelpURI = "https://stealthpuppy.com/VcRedist/save-vcredist.html")] [OutputType([System.Management.Automation.PSObject])] Param ( [Parameter(Mandatory = $True, Position = 0, ValueFromPipeline)] [ValidateNotNull()] [System.Management.Automation.PSObject] $VcList, [Parameter(Mandatory = $False, Position = 1)] [ValidateScript( { If (Test-Path -Path $_ -PathType 'Container') { $True } Else { Throw "Cannot find path $_" } })] [System.String] $Path = (Resolve-Path -Path $PWD), [Parameter(Mandatory = $False)] [System.ObsoleteAttribute("This parameter should no longer be used.
