over the past couple of weeks I have been experiencing difficulty with my presentation not running. they will run in Powerpoint viewer or if I copy them on to a memory stick and transfer them to my second laptop they run fine. Anyone any suggestions?

You need to give as much info as possible Harold.

What does "not running" actually mean? What do you see on the screen?

Hi when I go to slide show, which ever slide I bring up opens as normal but will not advance to next slide or next animation. This has only happened over the past couple of weeks. I have been using powerpoint for over 10 years and have never had this happen before

Couple of things to check

Slide Show > Set Up Show ... Make sure Show at a Kiosk is OFF
Animation Tab > Make sure Advance Slide on mouse click is ticked
