Hello!

I have some problem with my created nsis setup. I need to check if the product is already installed and then get the path to the already installed product. This is because I want to build a "Feature-Setup" that installs some other components into the previous installed folder. Does anyone know how to build this installer? It will be brilliant if the feature setup will start the installation and check the path of the installed product. After checking is done the path should be (read only) in "Destination Folder" under "Choose Install Location".

Thanks for any help
Buba
