If you have Swiff Point Player add-in for PowerPoint installed, you may find that some Presenter '09 features do not function as expected, such as the Send to Articulate Package feature. It may also interfere with the PPTA file and even cause loss of resources, such as audio.
The standalone Swiff Point Player is a legacy product from GlobFX.
To avoid conflicts between Swiff Point Player and Presenter '09, it is recommended that you do one of the following:
Disable the Swiff Point Player add-in while working with Presenter '09.
Upgrade to the latest version of Swiff Point Player, which is now part of ShowRoom.
