If you download rar files you will need a unzipping program to open the file. rar is just a different zip extension. the game will be inside the folder after you have opened it. you can go to snapfiles.com to download a unzipping program that opens rar files and if thats not what you mean you'll have to provide more detail. do you mean you got the rar file open and you cant run the game or do you need to unzip the rar file?
