If you receive this error while running a built installation package:
"The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2714."
..it means that the path specified for the installation package is incorrect. There is nothing the user can do about this since it's a problem with the package itself. Basically, ensure that the DefaultLocation property is correctly set to the full path of the directory to create and that the path is valid. The '(Name)' property is actually not used to name the folder on the target computer, it is rather an internal name used in the installer.
