Because of old installations, TeamViewer is sometimes installed in the 64 bit version and sometimes in the 32 bit version. Since I would like to have a clear overview in Intune, I created the script below.

$tv = "C:\Program Files\TeamViewer\TeamViewer.exe", "C:\Program Files (x86)\TeamViewer\TeamViewer.exe"
$result = ($tv | Test-Path) -notcontains $true

if ($result) {

    exit 1
else {
    write-output "Teamviewer detected, exiting"
    exit 0
