--- Comment #31 from Alistair Leslie-Hughes leslie_alistair@hotmail.com 2010-11-26 02:35:06 CST --- The Installer, when registering COM objects installs the overrides once (installing again wont change the overrides) if it detects WINE.
native msxml4 allows the application to without errors.
You will need to remove the override on the EA entry in winecfg. Enterprise Architect will crash when opening or creating a project.
