check for WinFX Runtime availability

How would I detect whether the WinFX runtime (in a certain version) is installed on the target machine in a culture- and OS-independent way and doing it with unmanaged code (preferably using vc++ 6)?

on x86 check for the reg key hklm->software->microsoft->winfx runtime->3.0->setup
on x64 check for the reg key hklm->software-> WOW6432node->microsoft->winfx runtime->3.0->setup
For these reg keys installsucesss should be set to 1
