In general the MsiSetExternalUI related stuff is available with a NET interop layer that wraps MsiExternalUIRecord. For example, you can arrange to handle FilesInuse events (search for ExecuteFilesInUseEventArgs) and display the dialog. Or search for BootstrapperApplication.ExecuteMsiMessage.
The MSI install must be completely silent for MsiProcessMessage to send its messages to nowhere or to an external UI handler. As much as we all like the convenience of wrappers that allow managed code to play in this environment or expand functionality with things like WcaErrorMessage there's always going to be some potential uncertainty about what's going on inside the handy black box. I imagine that three of the Win32 message types INSTALLMESSAGE_ERROR, INSTALLMESSAGE_FATALEXIT, and INSTALLMESSAGE_WARNING will map to separate events in the managed code, presumably with similar sounding names so people can do some mental mapping of what's going on, but maybe you're processing an error message when you should actually be processing a fatal error exit instead, something like that anyway. The only way to find out might be to process every event and log it, if you're not already doing so. --------------- Phil Wilson On Wed, May 14, 2014 at 5:36 PM, Phill Hogland <phogl...@rimage.com> wrote: > I have been following this thread and trying to figure out a similar issue > using WcaErrorMessage in my CA and trying to catch the error event and > display a message in my Burn mba.
