    Here is what I've done so far to handle 3 separate instances upgrading:

    <InstanceTransforms Property="Upgrade">
      <Instance Id="I01" ProductCode="*"  ProductName="Product Instance 1" UpgradeCode="55a25a09-5979-438d-91dd-67755012a288"/>
      <Instance Id="I02" ProductCode="*" ProductName="Product Instance 2" UpgradeCode="a27eb2e5-9aa8-4d09-b6c0-df717875c310"/>
      <Instance Id="I03" ProductCode="*" ProductName="Product Instance 3" UpgradeCode="d705720d-3703-4b17-817e-bd51edd9abea"/>
    </InstanceTransforms>
    

    While my Property Upgrade is a fixed Guid. With this, I can handle 3 instances with their updates separately using this line -for new installs, add MSINEINSTANCE=1- :

    msiexec /i MyProduct.msi MSINEWINSTANCE=1 Transforms=":I01"

    Pretty sure you need the product code for this since the upgrade code identifies a family of products, and not a single one.

    Fire up PowerShell and run this command to get a list of installed products with product code:

    Get-WmiObject -Class win32_product
    

    Here is a different way to get the output in a tabular format (IdentifyingNumber is ProductCode):

    Get-WmiObject Win32_Product | Format-Table IdentifyingNumber, Name, Version
    

    You can also find the product code in the Property table of the compiled MSI using Orca (MSI SDK tool):
