Norton Internet Security Disabled.

I am working on a fiends laptop. He caused a problem and i went into Sfe Mode and did a satisfactory system restore. The norton Int. Security on the machine is up to date but it is disabled. in fact it is the "Intrusion protection" that is off. Have tried the "FIX" button butoon it returns "Cannot fix"

I'm sure I have met this before but cannot rmemeber what to do to enable Norton properly. Any help much appreciated

Thanks
