Question

[barbarakewl]

I have a question about Setup Factory (Sorry for my bad english).

In Startup, from Actions, I want to control if the program which I want to have installed, already exists on the computer of the customer. If the programm allready exist A Message Box appears with the message that the programm allready is installed.
How could I do that? I can't find the right variables and operators.

In your initial install, did, or do you create any Registry entries that you can read that would provide information on whether it has been installed previously?

If not, you could potentially perform a file search for a specific file that your application uses in order to determine that information.
