Remove all versions of LogMeIn software

Question

I'm creating a VBScript to remove all found instances of LogMeIn Software. It seems to work installing but it is leaving the registry key. If I run the string manually from the cmd prompt it completely uninstalls, including removing the registry key. What do I need to do to not just execute the MSI uninstall but to also clean up the registry? Thank You

How many instances? Are they using the same upgrade code? You can uninstall all instances by the single upgrade code if so. Here is an example: Powershell: Uninstall application by UpgradeCode .

UPDATE : C# / .NET version .

There is also the Windows Installer PowerShell module from Heath Stewart .

Here is a proposed script inlined - I haven't tested it for reboot scenarios. Just leave the product open and uninstall and see if it triggers a reboot. Invoke via cscript.exe for silent running:

Const msiUILevelNone = 2
Const msiInstallStateAbsent = 2

Set installer = CreateObject("WindowsInstaller.Installer")
'installer.UILevel = msiUILevelNone ' Disabled to prevent silent uninstall. Now the UAC prompt will show

' Uninstall Orca, replace upgrade code with yours
Set products = installer.RelatedProducts("{UPGRADE-GUID-GOES-HERE-000000000000}")

For Each product In products
   ' MsgBox "Product Code: " & product ' Show the product code found, if you want

   ' The following call when run silently with admin rights may reboot the system without warning!
   ' This is due to badly authored MSI packages - most packages will not trigger this problem.
   installer.ConfigureProduct product, 0,  msiInstallStateAbsent ' Uninstall product

   ' See text above for info on the newer ConfigureProductEx method.

Set installer = Nothing

MsgBox "Finished" ' Just so we know the script ran if nothing found to uninstall
