The Powerpoint presentation runs 24/7 on an internal tv system. It shows the logo's and adds of the sponsors. The request is to add an tour after every 8 to 10 images. Just a single tour in autorotation mode. After a few rotations the slide show picks up again.
I do not know why a package in html does not work.
My understanding of Powerpoint is very limited.
Maybe they can use something like this to integrate your PT/PTP 1.8 Flash files?http://www.globfx.com/products/showroom/
If it wasn't a requirement to 'embed' in Powerpoint I might have suggested this:http://ww2.360panotours.com/
The request I received was if I could deliver several tours as mp4 movies.
Have a look at: demo.kempesfotografie.nl/hercules
In my opinion if the client wants video is it easiest to shoot video. Converting virtual tours to video is far from easy and the results are seldom very good.
