won't this miss if Symantec ever ships a 64-bit SEP? do they ship one already
that we're missing?

We're only checking for anything before 11MR3, which was 32-bit only and from
2008.

groovy. sounds like good info for a comment in the code. ;-)

Done.

   key.ReadValue(L"ProductVersion", &version_str);
