After I applied the patch for NIS 2013 and the patch was sucessfully applied the patcher stated "explore" at the bottom instead of "reboot'".  When I clicked "explore" nothing happened.  NIS 21`03 did not seem to be active.  I clicked on NIS in my Windows 7 (64 bit) start menu but it did not launch.  I needed to do a reboot to get NIS to work.  This happened on two computers.
