How to Uninstall Webex Active Touch Meeting Client

Cisco Webex comes with several installers which might seems a bit confusing for most of the system admins. Here is a quick overview of different installers available.

Options	App Type	Description
1	Mini Installer	– Supports user context or system context installation – Can start desktop webex app (to create meetings etc) – Can managed via winget (For user context installation, winget must be run in the same user context)
2	Webex Meetings desktop app (Webexapp.msi)	– Supports system context only – Can start desktop webex app (to create meetings etc) – Can be managed via winget – See command line options here
3	Webex.msi	– Supports user context or system context installation – Can start desktop webex app (to create meetings etc) – Can managed via winget (For user context installation, winget must be run in the same user context) – See command line options here.
4	Webex via Meeting Link	– It’s downloaed and installed instantly upon first meeting join (File name for example is WebEx_mc_YourCompanyName__YourCompany.webex.com_RandomCharacters.exe) – Cannot start desktop webex (to create meetings etc). Only joing meeting via the link is supported.

Options 1 to 3 allow for a smooth and automated upgrade or uninstallation process without user intervention. However, Option 4 involves an uninstall command that requires user confirmation, which makes it difficult to automate.

"C:\Users\YourUserName\AppData\Local\WebEx\atcliun.exe" /x MEETINGS LANGUAGE=EN

I couldn’t find the relevant uninstall command to avoid user intervention. So, the workaround is to delete the folder WebEx folder under this location

C:\users\YourUserName\AppData\Local

and delete the registry key

HKEY_USERS\YourSID\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ActiveTouchMeetingClient

Here is the powershell code to delete the folder and associated registry keys.

## This script will remove the Active Touch Meeting Client of Webex which was installed during the first-join of Webex meeting link ##

# Get the SID of the current user
$UserSID = ([System.Security.Principal.WindowsIdentity]::GetCurrent()).User.Value

# Define the registry path
$registryPath = "Registry::HKEY_USERS\$UserSID\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ActiveTouchMeetingClient"

# Define the folder path
$folderPath = [System.IO.Path]::Combine($env:USERPROFILE, "AppData\Local\WebEx")

# Check if the registry key exists or delete if exists
if (Test-Path $registryPath) {
    Remove-Item -Path $registryPath -Recurse -Force
    Write-Output "Registry key deleted successfully."
} else {
    Write-Output "Registry key does not exist."
}

# Check if the folder exists or delete if exists.
if (Test-Path $folderPath) {
    Remove-Item -Path $folderPath -Recurse -Force
    Write-Output "Folder deleted successfully."
} else {
    Write-Output "Folder does not exist."
}
