To install this program, create a new folder - any name will do, I call mine 'Slide Show'.  It can be on any hard drive.  Put the 'BROWSER.exe' file in that folder.  When you run it for the first time it will create a text file called 'portfoli.prt' in your folder.  Then start adding images from within the program - it's as simple as that.  You can create new folders with a name of your choice. - it's all in the 'Instructions' menu.

Enjoy!
