I downloaded the latest version but when I try to unzip it all it does is give me an error messege that says "The archive is either in unknown format or damages" 
I have downloaded it twice just encase but it keeps giving me the same error.

Also, for some reason this thing keeps deleting itself.

I use winrar and it unpackages without a problem. There is an exe inside.

If it doesn't work with Winrar use 7zip. Worked fine for me. As for the software, simply clic "RIFE-App.exe"
