No, it only needs DLL overrides if the combustion plugin is left in place. I slowly narrowed it down over the past few days to which DLL's are needed to get past the splash screen, and they would be the two mentioned in the attachment: ole32.dll and riched20.dll. Using native riched20 makes the messages about richedit functions that haven't been implemented yet go away, and ole32 keeps the program from locking up
When these DLL overrides are used, it loads up the splash screen and loads the plugins like normal, but instead of locking up when it reaches the combustion plugin, it says the plugin could not be loaded, then continues on, loads up most of the window, and crashes. Basically, it's possible to get past the plugin using native DLL's...but the app won't work.
I'll try to clarify this better on the appDB.
