Installed softare without GUID

Hi All,

We have an installed software on our PC's that don't have a guid. This means that when we try uninstall the product using powershell:

$app = Get-WmiObject -Class Win32_Product | Where-Object {
    $_.Name -match "Software Name"
}
$app.Uninstall()

the uninstall fails as it cannot find the product.

Is there a way we can manually assign a guid to the installed software?

also is there another way we can uninstall the product?

thank you in advance

Use the freeware version of Revo uninstaller in hunter mode.

If the software was not installed using an msi package you won't be able to uninstall it with $app.Uninstall(); Try locating the software in "Programs and Features",

If it can be found there you can find the uninstall string in the registry somewhere under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall or HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

When you find the uninstall string in the registry, go from there; If it is an MSI you can uninstall silent with msiexec /x {productcode} /QB, if the product has it's own uninstaller try to figure out if it has any command line options.

Can you give a hint about what software you are trying to uninstall?
