i develop a update .exe and its on a web server. when i start my main program,
it'll query the version first.if there is a new version on the web server, it'll create a process and execute the update .exe. whats the update doing is that downloading the new setup.msi and setting up automatically.i use the the api MsiInstallProduct(path,"action=install"). but there's someting unfriendly,
it'll popup the setup dialog and make the user to choose to restore or to delete. how can i make it to execute reinstallation action directly. msdn says the second parameter mapping to an action,but i just dont find anyting userful. help me .plz
thank u in advance.
there'r 2 cases. one maybe means a "patch" for adding some more resources.
in the other case , i need an entirely new version. my question is about the second case.
so i want to take a solution of reinstallation,though, im not sure whether its resonable or not...
and i cant understand whats ur mean about authoring my msi's.
