The installation for Frogger 2 is likely a 16-bit application, which are not supported on 64-bit versions of Windows.
Unfortunately, this only leaves you two options: Find if someone has written a 32-bit or 64-bit installer (this has happened for Grim Fandango and a few other games) or use a Virtual Machine.
Having said that, Virtual Box's Direct3D support was limited to DirectX 8 and 9. Unfortunately, this means that older titles do not work on it.
VMWare Player appears to support DX7 and earlier, but it has a somewhat intrusive signup process even though it's a free app, which involves them annoyingly sending you an email newsletter.
