Advice on installing BO2

[gomonarchs]

So I tried torrenting BO2 off of FitGirl and am having trouble actually installing the game on my computer. It keeps saying I have an unsupported compression type but I don't know how to fix that for a non-media file. It's also spitting out tons of error codes. Any advice would be greatly appreciated.
Error codes for future reference
-2, unsupported compression method
unable to execute file, CreateProcess failed; code 2
