I don't think its possible to have more than one NINJARMM Agent installed, however if there are this script will likely fail, but for a clean ninja install will locate the correct uninstall path and uninstall the ninja agent.

 

$UninstallString = (Get-ItemProperty HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\NinjaRMMAgent*).UninstallString

Start-Process -FilePath "$UninstallString" -ArgumentList "--mode unattended"

 

Revised script, the (x86) was causing issues, this seems to have fixed

 

$UninstallString = (Get-ItemProperty HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\NinjaRMMAgent*).UninstallString

$path = $UninstallString -replace "uninstall.exe", ""

cd $path

Start-Process -FilePath .\uninstall.exe -ArgumentList "--mode","unattended"
 

Darn, the MSI and agent both need to be removed, I wrote this to finish it up, but if anyone has a better way or can assist with a loop to pull both keys in one pass, I'm just tired. and this worked and all are removed from 500 stations with this one so I don't need it any more. I'd sense used the Get-ChildItem to uninstall several other programs, but I know it will pull more than one path so I'd love to re-write this to loop thru all the possible msi and exe and hit them both in a few lines rather than this, but it works as is, any input from someone more knowledgeableble than me please, I'm not proud.

 

$UninstallString = (Get-ItemProperty HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\NinjaRMMAgent*).UninstallString

sleep -seconds 2

if (!$UninstallString) { exit }

sleep -seconds 2

$path = $UninstallString -replace "uninstall.exe", ""

sleep -seconds 5

cd $path

sleep -seconds 5

Start-Process -FilePath .\uninstall.exe -ArgumentList "--mode","unattended"

sleep -seconds 40

$Uninstall2 = Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Where-Object {$_.DisplayName -match "NinjaRMMAgent" } | Select-Object -Property UninstallString | foreach { $_.UninstallString }

sleep -seconds 220

$Uninstall3 = $Uninstall2 -Replace "MsiExec.exe " , ""

sleep -seconds 5

Start-Process -FilePath MSIExec.exe -ArgumentList $Uninstall3,"/quiet","/passive"
