Can't run debug build

[zerox029]

I'm trying to help with some issues.
I downloaded the zip file, unziped it and opened osu.sln with visual studio.
However, it's telling me that the osu frameworks are unexistent and when i try to run debug it's telling me the following : Visual Studio cannot start debugging because the debug target 'c:\target' is missing. Please build the project and retry, or set the OutputPath and AssemblyName properties appropriately to point at the correct location for the target assembly.

Anyone knows how to fix?

Please learn how to git before trying to help. You won't be able to help by downloading a zip file.
