build error

I'm new to .Net so I hope I'm explaining this clearly.

I have a 5 project solution in VB .Net 2005. After adding a setup and deployment project to my solution, I am getting the build error below. The new install project is not included in the build process. I was not receiving this error before adding the project and I don't get it everytime I build, normally just the first time. After that, I can build fine.

Any ideas are welcome. Thanks!
