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

How to Create a Custom Detection Script for EduPython

EduPython (File Detection Method)

## Check for EduPython (File Detection Method)
$EduPythonExe = (Get-ChildItem -Path "C:\EduPython\App\PyScripter.exe"-ErrorAction SilentlyContinue)
$EduPythonExe.FullName
$EduPythonPath = $($EduPythonExe.FullName).Replace("C:\","")
$FileVersion = (Get-Item -Path "$($EduPythonExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with EduPython File Detection Method
$FilePath = "C:\Windows\Temp\EduPython_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:HomeDrive\$EduPythonPath`" -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 EduPython Detection Method script required to detect the current version of EduPython that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:HomeDrive\EduPython\App\PyScripter.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "3.6.3.0"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

EduPython (Registry Detection Method)

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

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

Example:

If((Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\EduPython_3.0_is1','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\EduPython_3.0_is1' -Name DisplayName -ea SilentlyContinue) -ge 'EduPython 3.0') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
