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

How to Create a Custom Detection Script for Anaconda

Anaconda (File Detection Method)

## Check for Anaconda (File Detection Method)
$AnacondaExe = (Get-ChildItem -Path "C:\ProgramData\Anaconda*\Uninstall-Anaconda*.exe" -ErrorAction SilentlyContinue)
$AnacondaExe.FullName
$AnacondaPath = $($AnacondaExe.FullName).Replace("C:\ProgramData\","")
$FileVersion = (Get-Item -Path "$($AnacondaExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw

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

Example:

If([String](Get-Item -Path "$Env:ALLUSERSPROFILE\Anaconda3\Uninstall-Anaconda3.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge "2022.5.0.0"){
Write-Host "Installed"
}

Anaconda (Registry Detection Method)

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

## Create Text File with Anaconda Registry Detection Method
$FilePath = "C:\Windows\Temp\Anaconda_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($Anaconda.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($Anaconda.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($Anaconda.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the Anaconda Detection Method script required to detect the current version of Anaconda that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Anaconda3 2022.05 (Python 3.9.12 64-bit)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Anaconda3 2022.05 (Python 3.9.12 64-bit)' -Name DisplayVersion -ea SilentlyContinue) -ge '2022.05') {
Write-Host "Installed"
}
