XML Error in the Setup project file with extension .InstallState

I recently upgraded from VS 2010 to VS 2013. I also installed the new Microsoft Visual Studio Installer that was able to compile my .vdproj ( setup project file). But there is this file in the setup project myproject.InstallState. The install program complains that the "Soap: Envelope XML element is missing a type attribute" I did not generate this file manually and I don't know how to regenerate it. But here is the entire file . Can some one figure out the error?
