Your second answer is useful for a Windows user but, as I described, I'm using an iMax OS X, version 10.7.5.
On an iMac it is impossible to use .exe files, nor does the Realplayer react on .exe or .ISO files.
How can I convert .ZIP or .ISO files into the original AVI or WMV format? These codes are being recognized by the iMac and Realplayer can play the video.
Thanks ahead for your reaction.
