Uninstall script not performing correctly

问题:

This is a really simple script that just uninstalls an application. Here is my code:

$app = Get-WmiObject -Class Win32_Product -Filter "Name = 'Alliance Suite G5'"

Write-Host $app

$app.Uninstall()

I put the Write-Host in just to make sure it was grabbing the correct application. Here is my output.

\COMPUTERNAME\root\cimv2:Win32_Product.IdentifyingNumber="{99B66721-7E75-487C-A0C8-A4F8C4325661}",Name="Alliance Suite G5",Version="2013.2.14226.1"

The return value is 0, but it never actually uninstalls the application. Any help would be appreciated! I run some automated tests at night and one of them installs the application so it would be nice if I could make a scheduled powershell script to uninstall it.

回答1:

It appears this is an Installshield suite project - essentially a collection of MSI files treated as a single product via some custom Installshield constructs. It appears to be a setup.exe type launcher that also is registered to handle ARP repair / modify.

In chat JLott confirmed that this command worked:

Alliance.G5.exe /remove /s

Full command used by JLott:

C:\Windows\system32>Start C:\AllianceInstall\G5\Alliance.G5.exe /remove /s

In addition to the above, you should be able to uninstall each individual MSI by finding its GUID and uninstalling via msiexec.exe.

This simple powershell command will provide a list of installed products with "identifying code". You can pass this code to Windows installer like this: msiexec.exe /x {GUID-HERE}

get-wmiobject -class Win32_Product 

Or you could select to view it in list form:

get-wmiobject Win32_Product | Format-Table IdentifyingNumber, Name, Version

回答2:

You must verify that the product actually uninstalls correctly in the first place. Please try to read the following article and test the uninstall in different ways: Uninstalling MSI files

I would recommend trying to log the whole uninstall and see what the log says:

msiexec.exe /X "C:\Install.msi" /QN /L*V "C:\msilog.log"

or if you have the GUID (see linked article above for how to find it):

msiexec.exe /X {YOUR-GUID-HERE} /QN /L*V "C:\msilog.log"

回答3:

Why is that msiexec command pointing to an executable? That's incorrect. You use the /X command passing the ProductCode. You must use that if you don't have the original MSI file.

This vbscript will list all the installed MSI products on the system, reporting their names and ProductCodes. Use it to find the ProductCode and use it in an msiexec command, if that's the direction you want to go. Save it as .vbs file and run it.
