Message: uistub.exe unpecified error

Hi,

 

Can you help?  Norton 360 isn't starting up on my laptop but instead gives this message:

 

c:\Program FIles (x86)\Norton 3360\Engine64\6.4.0.9\uiStub.exe Unspecified error

 

It's installed on a VIAO laptop, working with Windows 7 64bit.  It was not preinstalled.

 

With thanks in advance for any guidance!

 

Best wishes,

Caroline
