[Wine] Error on opening, Non 7z Archive

[zerogeer6]

I downloaded a game that I play on my Windows machine hoping to play it on my Linux machine and each time I try installing/opening I get an error that says Non 7z archive. I have tried a few different ways of opening this file to be immediately greeted with this error. Any ideas what is the cause of this? It is a larger .exe file at 2g in size. 

Thanks.
