Hi, I have a mac but it just unstuffs the .zips but doesn't put the subfolders anywhere so I have to install them manually. I'm trying to use my husband's computer to install all my.zip files into a single runtime folder that I can then take across to my computer and convert to mac then use from poser 5. the problem is that when I use winzip although some of the .zips seem to install hapilly into the right places, some of them just create a folder with all the subfolders inside it that sits inside the runtime folder, instead of in their correct subfolder places. I don't know if I've explained the problem very well. I'll try again. Basically some .zip files install themselves into my runtime normally and some just make their own folder and the subfolders aren't installed. Love esther
