Using PowerShell to detect and remove certain type of software - powershell

Question

I wish to modify the below script that used to be working, but now it is not working.
The purpose of this script is to uninstall and remove all Microsoft Office 2010, 2013, 2016 any version (Standard or Professional) 32 and 64 bit.
Write it to the log file when failed.
This is the script below that I've tried to modify but not working:
$AppDisplayName = 'Office'
$TARGETDIR = 'C:\LOGS'
$global:uninstallLog = Join-Path $TARGETDIR uninst.log
$WhatIfPreference = $true
$global:ShouldProcess = $false
$savedVerbosePreference = $VerbosePreference
$VerbosePreference = 'Continue'
$VerbosePreference = $savedVerbosePreference
$WhatIfPreference = $false
function Write-Log {
Param (
[Parameter(Mandatory)]
[String]$Message,
$Color = 'Green',
[string]$logfile = $global:uninstallLog
)
Process {
$msg = '[{0:dd\MM\yyy HH:mm}{1}' -f [datetime]::Now, $Message
if($logfile){$msg | Out-File $logfile -Encoding ascii}
$msg | Write-Host -ForegroundColor $Color
}
}
function Get-UninstallInfo {
Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall |
Get-ItemProperty |
Where-Object { $_.DisplayName -match $AppDisplayName}
}
New-Item $TARGETDIR -ItemType Directory -Force
Get-UninstallInfo |
ForEach-Object{
Write-Verbose "Processing $($_.DisplayName)"
Try {
if ($_.DisplayName -match '365') {
Write-Log "$($ENV:COMPUTERNAME) is already using O365 , no need to uninstall"
} else {
if($_.UninstallString -match '{(.*)}'){
$productCode = $matches[1]
Write-Log "Non Office 365 Detected - $productcode - Querying Uninstall command"
$arglist = '/x', $productCode, '/qn', '/norestart', '/L*v', $uninstallLog
Write-Verbose "ProductCode is set to $productCode"
if($ShouldProcess){
Write-Log "Uninstall command detected as $($_.UninstallString) Attempting silent uninstall"
Start-Process msiexec.exe -ArgumentList $arglist -Wait -NoNewWindow -ErrorAction Stop
} else {
Write-Verbose '"$ShouldProcess" is set to "$false"'
}
} else {
Write-Log 'Product code not found' -Color Red
}
}
}
Catch {
Write-Log "Error: $($_.Exception.Message)" -Color Red
}
}
This is the error log:
The "=" operator is missing after a named argument.
