Heya
Whomever you purchased Fort Zombie from in the first place is the place to go to for the updated version.
I am surprised to see that you downloaded the "patch" from SoftPedia, as they are not a Digital Distributor.
And given that FZ 1.0.4 is the entire game and not just an update, I sincerely doubt that they are allowed to just give it away like that...

It is perhaps possible that they diff'd the installs to supply only the modified files for their "patch", but then it is also possible that the file supplied is full of trojans and other malware...

Regardless of what the file they supply is, I can tell you that it is not supported now, nor will it ever be.
Again, I refer you to your original purchase. The folks who supplied that are the ones you want to get the "patch" from.
