Setup has determined that the Media Player MPLAYER.EXE is currently running.
This may cause problems if you attempt to install Microsoft Video for Windows.
The Microsoft Video for Windows Setup program needs to use some of the files that MPLAYER.EXE is using now.
You should select 'Cancel' from the next screen, and close Media Player before you rerun Morphology 101 Setup, or don't try to install Microsoft Video for Windows while MPLAYER.EXE is running.
