Where can I download a freeware version of 'The 7th Guest'?

I've looked all over freeware and abandonware sites, but I haven't been able to find it. I've only found the freeware version of 'The 11th Hour' (which I already own), which doesn't make sense considering that it's the sequel. So, logically, a copy of the first game must exist, right? Does anyone know here I can find it?
