run a setup on a setup program

[joaof]

When I am running my installation, I need to run a setup program to install some bought components.
So, to do it I paste into the Application Folder the entire folder which has the program, and at Custom Actions Editor, I created a custom action which runs the Setup.exe File.
Till here everything all right, but It appends one thing that I don

It seems odd that you should have to run the third-party setup manually, usually they provide a redistributable unit (such as a .ocx or .dll) that you can just bundle in to your setup.

If it really is the case, then a custom action would be the way to go, I think.
