Hi there,

I have a product (myProduct.msi) that comes with a sparate installer myPart.msi. At install time (if the user selects this) myPart.msi is installed together with myProduct.msi.

Now I have new versions of the myPart.msi and myProduct.msi. When I do a minor upgrade of myProduct.msi I need to do also a minor upgrade of myPart.msi but only if myPart.msi is installed. If myPart.msi is not installed I should not do any new installs of myPart.msi.

My question is how do I see in myPart.msi is installed on the computer? For this myPart.msi I know the Product Code, Upgrade Code, Package Code and Product Version. I think the best way is to write some Install Shield Script code for this and create an Install Script custom action.

Thanks for your help.

You could use the Upgrade table with the Detect Only option.
