Install Error: The name: <blank> is not valid. Please reenter it.

This is a permissions issue.    The user does not have the proper permissions to install the GFS program which can often be the case on the 64bit Version of Windows Vista/7/8.

Two possible solutions:
1. Try using the "Run as Administrator..." option when opening the install program (gfssetup_<agency>.exe).
2. Give temporary administrative rights to the user attempting to install the software.
