Norton Identity Safe does not install

I have problem with installation on Windows 7 x64. Installation starts, but hungs before 'Account' step indefinitely with 'Starting services' (or something like that) message and spinning wheel. I tried few times, but to no success. If installator killed (it does not complete by any mean), seems something gets installed, as IE ask if toolbar shoul dbe installed. If enabled it also creashes IE, that is not able to load any page. Any idea?
