Decompressing RAR files

I just downloaded a .rar file and I'm using a app called UnRARX to decompress it. When I start decompressing, it runs but gives an error at the end of the decompress, asking for a passowrd. The file I downloaded included a password.exe file which I don't know what to do with. When I try running the password.exe file with Unrarx, it doesn't work. What do I do? HELP!

have you got stuffit installed sometime stuffit can get passwords from exe files if they are compressed if not then you prob need a windows machine to get the password

As far as I'm concerned, only Windows computer open .exe files. Which makes me wonder, why would the Mac app you download, use a Windows only extension to reveal the password? Proceed with care. Make sure you check for virus before you open the .exe file on a windows computer.
