I honestly can't seem figure this out from the log files :(

Here's my situation:
- I'm performing a major upgrade from msi 1.0 -> msi 2.0
- 2.0 has RemoveExistingProducts immediately after InstallInitialize
- 1.0 has a commit custom action that executes during an uninstall (by

It appears that the 1.0 commit action is getting executed at the end of the
2.0 install, not at the end of the 1.0 uninstall. Is this expected? Would
the 1.0 commit action get scheduled in such a way that it doesn't execute
until after the 2.0 finishes InstallFinalize?
