Hi there and very good day for all, I've got error message (start main dialog failed) after trying to reinstall kaspersky internet security , KIS indicates an application internal crash after the updates started after I entered licenes code (notably there were 7 days passed the expiration date of last licence) . So I unistall it and download the installer from kaspersky labs online, but unable to proceed. Some people said it is due to corrupt system files, I am not aware of them .
