cannot install nis on laptop restored to factory setting

I have a Dell 1525 laptop with windows vista home basic.  I restored it to factory settings using the system repair in the safe mode.  I installed all available windows updates.  Whenever I attempt to install NIS 2014, I receive the error message that the operating system is incompatible.  Any suggestions?  I also have a Dell 531s with Windows Vista Home basic and do not have any problems updating NIS 2014.
