Now I want to create another setup project which is very similiar, but with some changes.
Instead of creating a setup project again, which need lot of setting and arangmenets, I want to copy the setup project I have , of course to give it different name, and then to change only some parameters I need.
But how can I create a copy of project? because if I just change the name of the .prj file it won't be enough.
The only way would be you copy your Setup project1 to a new folder, and then rename the Setup1.vdproj to Setup2.vdproj, then you can right click the Visual Studio solution and Add->Existing Project..., select the Setup2.vdproj.
Now you can change the project name and others info.
