Sure can! Put some sort of autoshape (I use the top left Action Button) on
your slide. If you use an Action Button, when the "Action Settings" dialog
box comes up, click the "Run Program" option. Depending on the version of
Windows you have (I have Windows XP), you will need to enter the path to the
solitaire program. Something like:
C:\WINDOWS\system32\sol.exe
When you go into Slide Show mode and click the button, click "OK" to accept
the "Oh my god, the world is going to come to an end" dialog box that comes
up (sorry, getting a little melodramatic) and the game will start.
If you use something other than an Action Button, right-click the object and
select "Action Settings" to perform the above steps.
Of course, you can also put some sort of object on your slide, click
"Insert", "Hyperlink", browse to the same folder and select the "sol.exe"
file. This method, however, brings up two "Oh my god, the world is going to
come to an end" dialog boxes!
Holler back if you need help!
