Deploying A Solution

Trying to deploy my first solution and am having problems.

Following instructions per "SAMS Teach Yourself Microsoft Visual C# .NET 2003". Built a Picture Viewer project in Hour 1 and am currently in Hour 22 attempting to deploy the Solution I constructed in Hour 1.

To deploy my solution I have done the following:

1) Created a custom setup program (ie. Setup Project)
2) Added the output of my project.
3) Installed final executable of Picture Viewer project in Setup Project.
4) Defined the Build Configuration for the Setup Program as "Release Build".

The error I am receiving occurs when I then try to Build the Setup Program. The error reads: "Unrecoverable build error E:\MyProjects...Picture Viewer.vdproj". It doesn't provide me with any other info than that. The only thing I can think of is that the common language runtime (DotNetfx.exe) does not exist on user's machine.

Anyone else have similar problem when deploying solution or have any suggestions. Thx
