If you look at the built MSI, you'll see EventSource is just some syntactic sugar to express simple registry keys/values. Create a component in a fragment / wix library and mark it as shared. Then do a ComponentRef in your various installers and they will all "share" that component. Last one off will remove it.
Or you could just mark it as permanent and not worry about it so much. I probably would because any event log entries are likely to stick around long after your applications have been uninstalled. ---------------------------------------- From: keith.doug...@statcan.gc.ca Sent: Friday, March 22, 2013 10:09 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Event source sharing Hi everyone, I'm getting the hang of Util:EventSource, and I realized our original plan was to have several of our applications (which are all "of a kind" - they are a bunch of collection instruments which are from the perspective of installation more or less identical) share a source. If one MSI installs the EventSource originally, and another application attempts to install it ... (a) What happens on install? I seem to see that this collision is harmless. (b) What happens on uninstall of *one* of the applications? Is there reference counting so that this does nothing to the source until the last application is removed? Do they have to share components or anything like that for this to work, or is the naming sufficient?
