Question

How do I run an MSI, grab it's process id and get a return code?

Asked by: ndwHombre

I have a list of GUID's that I want to run through and uninstall.  The product may or may not be installed on the machine.  What I want to do is run an msiexec /x and then get  the result from the uninstall.  If the product is not on the machine at this point it looks like the msiexec process is still running and I need to kill it but I want to be sure it is the same Msiexec that I kicked off.

This is what I'm using to kick of the Msiexec:

Set WshShell = WScript.CreateObject("WScript.shell")
WshShell.Run "msiexec /x {GUID}"

I suggest trying

strReturn = WshShell.Run ("msiexec /x {guid}"), 1, true)

This will have the vbscript show the msiexec process, but wait until it is completed before continuing.  strReturn should be 0 if it suceeded.

I have heard others use code like below to uninstall a list of software:

On Error Resume Next
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
Set colSoftware = objWMIService.ExecQuery("Select * from Win32_Product Where Name LIKE 'nameofsoftwarehere%'")
For Each objSoftware In colSoftware
    objSoftware.Uninstall()
Next
