The demo installs PACE Anti-Piracy software along with the trial version of Movie Magic Screenwriter. Once this software is installed into a particular wineprefix, it will try to load a driver called TPkd.sys along with any program started from that wineprefix, not just the demo. I therefore recommend this demo be installed in a separate wineprefix from all other programs. Current Wine is able to load the driver and the demo is operational, however, it is not known whether the full version will run.
As of 1.3.8, there are no more error messages or problems with msxml3/msxml4 on startup.
If you are using an older version of Wine, upgrade.
