CF WEST Installing

Mainly two possible reasons : 
1. Bad storage area where dwnl files are saved - therefore install can't correctly read the info
OR
2. Installation file was incorrect dwnl from website (usual cause unstable internet connection or other programs running in background interfeering with dwnl process) - therefore when install extract game files give error

Best fix is to scan & fix your storage for bad blocks (just in case is the storage fault) then fresh install game using stept from here :
