It knows all your paths because given a ProductCode and a component guid it can use things like MsiGetComponentPath to find them. "it knows all your properties" is too general to reply to, but it certainly doesn't persist the values of properties that you create during your first install (unless they are standard properties persisted as part of its usual behavior, like MsiGetProductInfo can get your Manufacturer property, your version, company).

Write the stuff i need later in updates to the registry and retrieve it then again. I thought there must be a simpler solution and the installer does that automatically. Because when you repair installations it knows all your paths, properties etc.... Alex ------------------------------------------------------------------------ - Take Surveys. Earn Cash.
