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 Cisco Webex using PowerShell.
How to Create a Custom Detection Script for Cisco Webex
Cisco Webex (Registry Detection Method)
- Install the version of Cisco Webex you want to deploy on a test box or VM
- Check out the following posts for further details
- 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 Cisco Webex (Registry Detection Method)
$Webex = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'Webex' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$Webex.DisplayVersion
$Webex.PSChildName
## Create Text File with Cisco Webex Registry Detection Method
$FilePath = "C:\Windows\Temp\Cisco_Webex_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($Webex.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($Webex.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($Webex.DisplayVersion)') {"
Add-Content -Path "$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 Cisco Webex Detection Method script required to detect the current version of Cisco Webex that is installed on the device you are running the script from.
Example:
If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ED524209-34E2-5A93-AA34-3D044F86A2D5}','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{ED524209-34E2-5A93-AA34-3D044F86A2D5}' -Name DisplayVersion -ea SilentlyContinue) -ge '43.1.0.24716') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
- Copy the Cisco Webex Detection Method script content into the Custom Detection Rules (Script)
- Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM)
- Microsoft Intune
