.Synopsis Downloads a Cumulative Update from the Microsoft Download Center .DESCRIPTION Based on the Microsoft Dynamics NAV Team Blog, this function is going to download a cumulative update to a download folder. The function uses the download helper (Load-NAVCumulativeUpdateHelper) .PARAMETER CountryCode Optional, default is <blank> otherwise a NAV/BC supported country code .PARAMETER Version Required. A NAV/BC version. Acceptable values are 2013, 2013 R2, 2015, 2016, 2017, 2018, BC13, BC14, BC15. This uses pattern matching so there are no defaults, so future versions (e.g. BC17, BC20) are supported and can be used once the version is available and set up in the Versions.json (see SettingsFile) .PARAMETER CUNo Optional, default is <blank> otherwise a valid (cumulative) update number. If blank the latest update is downloaded If the update does not exist for the version specified then an warning is issued .PARAMETER Locale Optional, default is <blank> otherwise a valid NAV/BC supported locale .PARAMETER DownloadFolder Optional, default is $env:TEMP otherwise an existing folder where the downloaded file will be placed. .PARAMETER SettingsFile Optional, default is versions.json located in the same folder as the script. versions.json entries DefaultDownloadURL : the base url used for each update specific web page, "https://support.microsoft.com/help/" BuildRegex : the regular expression used to parse the build number from the update page title "Build (([\\d\\.]+))" CountryCodeRegex : the regular expression used to parse the country code from the download file name from downloads link, "\\.([A-Z]{2}|W1).DVD|(?:\\.)?([A-Z]{2}|W1)\\.ZIP" downloadLinkRegex : the regular expression used to parse the download link information from the specific update page "(https?\\:\\\/\\\/www\\.microsoft\\.com\\\/(?:[a-z]{2}-[a-z]{2}\\\/)?download\\\/details.aspx\\?(?:familyid=([\\da-zA-Z]{8}-(?:[\\da-zA-Z]{4}-){3}[\\da-zA-Z]{12})|id(?:%3d|=)?(\\d+)))" CUNoRegex : the regular expression used to parse the cu number from the support article description. "(?:Cumulative )?Update (\\d\\d?\\.?\\d{0,2})"" versions : Array of version objects, one object is required for each version to be downloaded version object version: required, the version number, must match the Version parameter used url : reguired, the url to the main released updates page for example the release cumulative updates page for NAV2013 is "https://support.microsoft.com/en-us/help/2842257" the Released Updates for page for BC16 is "https://support.microsoft.com/en-us/help/4549687" fileNamePrefix : required the prefix for the downloaded filename e.g. NAV for NAV.7.0.34587.DE.DVD.CU01.zip or BC for BC.16.0.12805.AT.DVD.CU16.1.ZIP downloadLinkRegex" : optional, if not specified the root downloadLinkRegex will be used. If there is some unique string that does not allow the default regular expression to be used. CUNoRegex : optional, if not specified the root CUNoRegex will be used. If there is some unique string that does not allow the default regular expression to be used. e.g. versions : [ { "version": "2013 R2", "url" : "https://support.microsoft.com/en-us/help/2914930", "fileNamePrefix" : "NAV", "downloadLinkRegex" : "" }, { "version": "BC16", "url": "https://support.microsoft.com/en-us/help/4549687", "fileNamePrefix" : "BC", "downloadLinkRegex" : "" } ], "Exceptions" : array of exeption objects. These are version CU combinations where there is a known problem. version : required, the version number in which the exception applies, must match the Version parameter used CU : required, the update number in which the exception applies. description : required, a description of what the exception is. This will be displayed as a warning. reference : optional, if present must be the url to a corrected download page productID : optional, if present must be the product id of the download version e.g. Exceptions : [ { "version" : "2013 R2", "CU" : 19, "description" : "Not available from Download Center. It is a hotfix file request instead.", "reference" : "", "productID" : "" }, { "version" :"2017", "CU" : 1, "description" : "Not available from Download Center. It is a hotfix file request instead.", "reference" : "", "productID" : "" } ] helpers : optional, array of websites that assisted with the creation of the required regular expressions and formatting them for JSON Thought they might be useful to others. { "name" : "Free Formatter Free Online Tools For Developers", "Description" : "Use this to escape/unescape strings for storage in JSON file", "url" : "https://www.freeformatter.com/json-escape.html" }, { "name" : "RegEx Editor", "Description" : "RegExr is an online tool to learn, build, & test Regular Expressions (RegEx / RegExp).", "url" : "https://regexr.com/" } .PARAMETER LogFile Optional, location and file name of where to put information from the web pages used to debug issues with regular expressions. Defaults to "Log\Version $Version Update $CUNo Country $CountryeCode Log.txt" (e.g. Log\Version 2015 Update 27 Country GB Log.txt) which is a sub-folder of the script folder If specified then the CreateLog parameter must also be set .PARAMETER ShowDownloadFolder Optional switch, Shows the download folder in File Explorer when the download is complete. .PARAMETER GetInfoOnly Optional switch, Do not download the file, only display the download information .PARAMETER SaveInfoJSON Optional switch, Saves the download information JSON file regardless of the GetInfoOnly parameter .PARAMETER PadEdition Optional switch, zero pads the Edition portion of the filename. Sorts better in File listing e.g. NAV.09.0.43402.CZ.DVD.CU01.zip vs. NAV.9.0.43402.CZ.DVD.CU01 .PARAMETER CreateLog Optional switch, creates log file specified in LogFile, If specified then the LogFile parameter must also be set .EXAMPLE Get-NAVCumulativeUpdateFile -version 2018 -CountryCode BE This example gets the latest update for Country Code BE (Belgium) for NAV2018 .EXAMPLE Get-NAVCumulativeUpdateFile -version BC15 -CUNo 7 -CountryCode FR -DownloadFolder 'C:\NAV DVDS\BC15' This example gets update 7 for Country Code GB (Great Britain) for Business Central 2019 Wave 2 (15) and puts it in the C:\NAV DVDS\BC15 folder .OUTPUT - Objects with info about the downloaded cumulative updates - optionally downloads update ZIP file - optionally a JSON file with details about the download #> function Get-NAVCumulativeUpdateFile { param ( [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName)] [String]$CountryCode, [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName)] [ValidatePattern("^2013 R2$|^201[3,5-8]{1}$|^BC1[3-9]{1}$|^BC2[0-9]{1}$")] [String]$Version = '2018', [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName)] [String]$CUNo, [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName)] [String]$Locale, [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName)] [String]$DownloadFolder = $env:TEMP, [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName)] [String]$SettingsFile = (Join-Path $PSScriptRoot 'Versions.json'), [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName)] [String]$Logfile = (Join-Path $PSScriptRoot $("Log\Version $Version Update $CUNo Country $CountryeCode Log.txt")), [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName)] [Switch]$ShowDownloadFolder, [Parameter(Mandatory = $false)] [Switch]$GetInfoOnly, [Parameter(Mandatory = $false)] [Switch]$SaveInfoJSON, [Parameter(Mandatory = $false)] [Switch]$padEdition, [Parameter(Mandatory = $false)] [Switch]$CreateLog = $false, [Parameter(Mandatory = $false)] [Switch]$skipExceptions = $false ) begin { } process { if (-not (Test-Path $SettingsFile)) { Write-Error "Settings file cannot be found at $SettingsFile." return } if (Test-Path $Logfile) { Remove-Item -Path $Logfile -Force } $CUNo = $CUNo.PadLeft(2, "0") Write-Verbose "" Write-Verbose "Processing parameters CountryCode: $CountryCode Version: $Version Update: $CUNo" Write-Verbose "Reading settings from $SettingsFile" $SettingsJSON = Get-Content -Raw -Path $SettingsFile | ConvertFrom-Json $VersionSettings = $SettingsJSON.Versions | Where-Object { $_.Version -eq $Version } if ($null -eq $VersionSettings) { Write-Error "No version information found for Version $Version in $SettingsFile." return } if (-not $skipExceptions) { Write-Verbose "Checking exceptions" $CUException = $SettingsJSON.Exceptions | Where-Object {($_.version -eq $Version) -and ($_.CU -eq $CUNo)} if ($null -ne $CUException) { Write-Error "$version $CUNo is an exception.
