Your best option is to use a script, in which you can test for the product's installed state using the WindowsInstaller.Installer object. If it's installed, do a repair. If not, install. The object model is fully documented on MSDN.
BTW, one of the big advantages of using the WI engine is that applications can self-heal, if the installation package is properly constructed.

this script will help you, we use it as a pre-req sometimes in sms to determine whether an app is installed or advertised and then uninstall it.
you'll have to change it a bit for your scenario but it's a start

Option Explicit
Const productCode = "{xxxx-xxx-xxxx-xxxxxxx}"
Const productFeat = "Complete"
Const msiProdAdvertised = 1
Const msiProdInstCurrUser = 5
Const msiInstallStateAdvertised = 1
Const msiInstallStateLocal = 3
Const msiInstallAllFeatures = 65535
Dim msiObject : Set msiObject = CreateObject("WindowsInstaller.Installer")
Dim objShell : Set objShell = CreateObject("WScript.Shell")
' Check existing product state
If (msiObject.ProductState(productCode) <> msiProdAdvertised) And (msiObject.ProductState(productCode) <> msiProdInstCurrUser) Then
' Package is neither advertised or installed so exit the script with error code 0 to satify SMS pre-requisite
WScript.Quit(0)
Else
On Error Resume Next
' If main product feature is either advertised or installed, call uninstall routine via msiexec command line
If (msiObject.FeatureState(productCode, productFeat) = msiInstallStateAdvertised) Or _
(msiObject.FeatureState(productCode, productFeat) = msiInstallStateLocal) Then
objShell.Run("msiexec.exe /x {xxxxx-xxxxx-xxxx-xxxx} /qb!"),1,True
End If
End If
