Hello! I FINALLY got verified to be in the forum!!! I have been using this software since somewhere around version 4. I have recently upgraded to 7...or whatever the latest is and i am wondering if anything has changed regarding this topic. I want clients to be able to see the show on their smartphones (mp4 files) and other formats than the usual EXE i used to make...BUT i SELL the slideshow so i need them to expire. So my question is...if i make an EXE file only but the kind that will also play on a Mac, and i put an expire date, will it work? All these years i have only made them as EXE files with an expire date and if a client had a Mac i just wouldn't make them one...now with more people having smartphones i wanted that other option...but not if the trial period won't work. THANKS!...also i am NOT very techy so in your reply, plain speak is easiest for me to understand =)
