Re: [WiX-users] Task Manager - Aborting

[Vagmi M. <vag...@gm...>]

Hi Uma,

This is the expected behavior of Windows Installer and is there for
good. The Windows Installer internally keeps track of all the actions
it did and creates a rollback script. So, regardless of any MSI
operation that is performed (barring repair, I guess), Windows
Installer will kick in and say that you have some uncommited changes
and would force you to roll them back before you make anymore changes
to that machine. So this always leaves your system in a consistent
state.

So this behavior falls under the category of **Its not a bug, its an
undocumented feature**. :-)
