I was looking for list of actions and their sequence when running a WiX setup. Somehow the official website doesn't seem to provide any information.

The basic problem is that I want to schedule my custom actions correctly. Typically I need to register a DLL with regsvr32.exe, and this can only be done once the files are copied to the harddrive. However the custom action

<Custom Action="RegisterShellExt" After="InstallFiles">

failed with the error message "file not found".

What I've done then is analizing the log of my MSI with WiX Edit, and I've found that the Action InstallFiles exists more than once. And effectively the files are written only the second time it appears. So I changed my custom action to the following :

<Custom Action="RegisterShellExt" Before="InstallFinalize">

Here is the sequence I've extracted from the logs of my MSI:

Action start 15:16:49: INSTALL.
Action start 15:16:49: PrepareDlg.
Action start 15:16:49: AppSearch.
