Create a Custom Detection Script for WizTree (PowerShell)


Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM) and Microsoft Intune use Detection Rules to determine the presence of Applications & Win32 Apps. The detection rules ensure that application installations only begin to run if the application is not already installed on the device. This article will serve as an informative guide and give you a clear understanding of how to create an updated custom detection script for each new version of WizTree using PowerShell.

How to Create a Custom Detection Script for WizTree

WizTree (File Detection Method)

## Check for WizTree (File Detection Method)
$WizTreeExe = (Get-ChildItem -Path "C:\Program Files\WizTree\WizTree.exe" -ErrorAction SilentlyContinue)
$WizTreeExe.FullName
$WizTreePath = $($WizTreeExe.FullName).Replace("C:\Program Files\","")
$FileVersion = (Get-Item -Path "$($WizTreeExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with WizTree File Detection Method
$FilePath = "C:\Windows\Temp\WizTree_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$WizTreePath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the WizTree Detection Method script required to detect the current version of WizTree that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\WizTree\WizTree.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "4.10.0.0"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

WizTree (Registry Detection Method)

## Check for WizTree (Registry Detection Method)
$WizTree = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'WizTree' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$WizTree.DisplayVersion
$WizTree.PSChildName

## Create Text File with WizTree Registry Detection Method
$FilePath = "C:\Windows\Temp\WizTree_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($WizTree.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($WizTree.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the WizTree Detection Method script required to detect the current version of WizTree that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\WizTree_is1' -Name DisplayVersion -ea SilentlyContinue) -ge '4.10') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
