Create a Custom Detection Script for KeyStore Explorer (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 KeyStore Explorer using PowerShell.

How to Create a Custom Detection Script for KeyStore Explorer

KeyStore Explorer (File Detection Method)

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

  - KeyStore Explorer Silent Install (How-To Guide)
  - KeyStore Explorer 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 KeyStore Explorer (File Detection Method)
$KeyStoreExplorerExe = (Get-ChildItem -Path "C:\Program Files\KeyStore Explorer\kse.exe","C:\Program Files (x86)\KeyStore Explorer\kse.exe" -ErrorAction SilentlyContinue)
$KeyStoreExplorerExe.FullName
$KeyStoreExplorerPath = $($KeyStoreExplorerExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($KeyStoreExplorerExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

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

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\KeyStore Explorer\kse.exe","${Env:ProgramFiles(x86)}\KeyStore Explorer\kse.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "5.5.1.0"){
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 KeyStore Explorer (Registry Detection Method)
$KeyStoreExplorer = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'KeyStore Explorer' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$KeyStoreExplorer.DisplayVersion
$KeyStoreExplorer.PSChildName

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

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{A771FBEB-F7E1-4443-9181-AFD57F7BFF45}_is1','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{A771FBEB-F7E1-4443-9181-AFD57F7BFF45}_is1' -Name DisplayVersion -ea SilentlyContinue) -ge '5.5.1') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
