question about bin file
 

Hello, this is prob a stupid question & doesn't belong in this forum but please help if you can.
lets say you DL the program Photoshop 7.0.....ran the .rars & made a 500 mb .BIN file (no cue file).....how would I install this?
don't know what to do next.....I tried to change the extention to .exe needless to say that didn't work......I'm sure it's something real simple I'm missing.....thx for any help
