Do I have to have PPT 2003 on the same computer that runs MagicInfo Pro or will it work if I just create the PPT in PPT 2003?
I have 2007 on the computer that runs MagicInfo, but I also have access to another computer that has 2003.
I'm not sure of the actual terms but lets call the software that runs on the display/sign itself the client. Lets call computer running the authoring/scheduling application the server.
To run the powerpoint in a window on the client, you need to have PPT 2003 installed. (For the newer signs with the hard drive, this should not be a problem. For the older flash based computers, space may be an issue. Haven't tried it yet.)
On the server, you don't have to have PPT installed at all, but it may help to have it installed so you can edit you powerpoints and so on. If you have 2003 it may preview correctly, but like you i have 2007 installed, so I get the navigation canceled and it PPT opens when I try to preview. But the sign works just fine.
