From what I have read is that the full version off PowerPoint needs to be installed. This is off the Xibo site but think these fixes would work with Magic Pro also.
Install Guide NET Client - Xibo
Windows Modifications
Here are some suggested settings for Windows / Powerpoint for a Display Client:
* Turn off all screensavers
* Turn off screen power saving
* Load the "No Sounds" Sound Scheme (Control Panel -> Sounds and Audio Devices Properties)
* Set a plain wallpaper (Hopefully nobody will see it, but you might need to reboot a client, or restart Xibo and a sane wallpaper is a help
* If the client is accessible from where you manage your displays from, you might want to install UltraVNC server so you can connect in and check on the client from time to time. Use the "View only" option in the VNC client to avoid disturbing the display.
* Set Windows to log on as your display client user automatically
* Disable balloon tips in the notification area
* Disable Windows Error Reporting. Occasionally Powerpoint seems to "crash" when Xibo closes it. Unfortunately this leaves an unsightly "Powerpoint has encountered a problem and needs to close" message on the display. Follow the steps here to disable Windows Error Reporting completely - including notifications.
* Also disable Office Application Error reporting. Follow instructions at KB325075 or merge this registry patch.
If you're using Powerpoint, then there are a couple of extra steps:
* The first time you run Xibo with a Powerpoint, you might get a popup appear that asks what Xibo should do with the Powerpoint file. The popup actually originates from Internet Explorer. Choose to "Open" the file, and untick the box so you won't be prompted again.
* In some circumstances, you may find that Powerpoint, the application, loads instead of the file opening within Xibo itself. If that happens, try merging this registry patch. (Taken from pptfaq.com). Users of Powerpoint 2007 should go to Microsoft KB927009 and run the FixIT application instead. Users of PowerPoint 2010 should go here instead KB982995
* Note also that Powerpoint will put scroll bars up the side of your presentation, unless you do the following for each Powerpoint file BEFORE you upload it:
o Open your Powerpoint Document
o Slide Show -> Setup Show
o Under "Show Type", choose "Browsed by an individual (window)" and then untick "Show scrollbar"
