"The install file cannot be properly validated"
I double click on the installer file icon for N360 v4.0, the install screen appears saying "initialising, please wait..." after a few seconds an error msg appears: "A problem has occurred that needs your attention, the install file cannot be properly validated".
I have had to endure almost 3 weeks of Norton tech support - yes 3 weeks!!! with no solution offered!!!
I / they have tried everything including all the removal tools / clean download etc... checked disk, uninstalled xp sp3 and reinstalled, checked file registry etc with no joy....
The digital signature is not being recognised as being valid by windows xp. I wonder if this is because the timestamp on the N360 install file digital signature is 27/03/10, but an xp security update (KB978601) issued on 13/04/10 changed the format of digital signature validation - effectively making previously good digital signatures invalid....?
Please help - Norton tech appear to be ignoring me
