Create a Custom Detection Script for Zotero (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 Zotero using PowerShell.

How to Create a Custom Detection Script for Zotero

Zotero (File Detection Method)

Install the version of Zotero you want to deploy on a test box or VM

  - Zotero Silent Install (How-To Guide)
  - Zotero Install and Uninstall (PowerShell)
Open Windows PowerShell ISE by Right-Clicking on Windows PowerShell ISE and selecting Run as Administrator
Copy the following code into the Windows PowerShell ISE

## Check for Zotero (File Detection Method)
$ZoteroExe = (Get-ChildItem -Path "C:\Program Files\Zotero\zotero.exe","C:\Program Files (x86)\Zotero\zotero.exe" -ErrorAction SilentlyContinue)
$ZoteroExe.FullName
$ZoteroPath = $($ZoteroExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($ZoteroExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with Zotero File Detection Method
$FilePath = "C:\Windows\Temp\Zotero_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$ZoteroPath`",`"`${Env:ProgramFiles(x86)}\$ZoteroPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$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 Zotero Detection Method script required to detect the current version of Zotero that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\Zotero\zotero.exe","${Env:ProgramFiles(x86)}\Zotero\zotero.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "6.0.15"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Open Windows PowerShell ISE by Right-Clicking on Windows PowerShell ISE and selecting Run as Administrator
Copy the following code into the Windows PowerShell ISE

## Check for Zotero (Registry Detection Method)
$Zotero = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'Zotero' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$Zotero.DisplayVersion
$Zotero.PSChildName

## Create Text File with Zotero Registry Detection Method
$FilePath = "C:\Windows\Temp\Zotero_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($Zotero.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($Zotero.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($Zotero.DisplayVersion)') {"
Add-Content -Path "$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 Zotero Detection Method script required to detect the current version of Zotero that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Zotero 6.0.15 (x86 en-US)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Zotero 6.0.15 (x86 en-US)' -Name DisplayVersion -ea SilentlyContinue) -ge '6.0.15') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
