I'm struggling with a very simple concept. I have one set of features that are installed to one user selected directory (INSTALLDIR) and I have another set of features I want installed to a different directory (USER_DIR2). What I can't figure out is when/how to set USER_DIR2 so the files are copied to the correct place.
I'm using MsiSetTargetPath to set the path but it is pretty clear I'm doing it at the wrong time/place. According to the log, the property gets changed but then it gets change back during CostFinalize.
I'm having a hard time getting a grip on all the custom action options as well as the ordering of actions. I thought setting a target path would be a good starting point to learn about them. Unfortunately, it has just lead to more confusion.
I found the solution to my problem. My custom action was after CostFinalize but what I didn't realize is that components, as well as features, had destinations. I had changed the feature destination, but had not changed the component destination. Once I did this my custom action and MsiSetTargetPath worked as expected.
I'm still more than a bit confused/overwhelmed by all the MSI stuff but at least now I'm making some progress.
