I have a minister going to brazil for a mission trip he wants to use
powerpoint slide he already has on a system that is in Portugues?
If he only needs to show the slides, it will work fine if he takes with him
a CD or USB stick with the presentation in PPT or PPS format. Plus any
multimedia files like sound or video. (Call them in advance, to make sure
which storage medium should be used and which version of PowerPoint they
use.)
If he needs to work on the slides in Brazil, he will have to cope with a
Portuguese keyboard and user interface - does he speak the language? But
technically, that should be no problem, either. There might be some issues
if they use an older or newer version.
Best regards,
Ute
