Wrong install path

setup

Hello,

I have a C# solution with a setup project. When I install or install on a another computer, the installation path is not takeing. The setup install is always on C:\

eg: if the user selects c:\tools\MyProgam, the setup installs the package on c:\

For information, in my solution I have a custom action, and I change the defaultLocation.
