I tried a search and found nothing so sorry if i've put this in the wrong place and what, not.

When i unzip my files, they have the bodyshop icon instead of clean installer.
Do you know how i change the file type?
I can't remember how i did it last time :/

thanks =)

Right click the icon and use the 'open with' option. I had that happen recently, and just had to set the option to always open with clean installer.
