Sorrry if I posted it in a wrong section but please help me</3

I downloaded Xtacsy today then I pasted it on my new folder... But when I double click it to extract it on a new folder it says it cannot open file in ______ as an archieve.. Please I really wanna try it out! =/

When you went to extract the client did you use the correct decompression tool, I personally use 7zip and it works fine.

What I mean is the XtacyFlyff File is a 7z SFX which is a 7-zip file, I would recommend downloading 7-zip and having another go, post if something goes wrong again.
