First, I'd look to see if the DifX framework supplies all this stuff without you needing to do it:
http://www.microsoft.com/whdc/driver/install/difxtools.mspx It sounds like you need to understand rollback custom actions. The basic idea is that if you create a bunch of registry entries in an install custom action, then you also need a rollback custom action that restores the system to its previous state, most likely by removing them. Sequence the rollback CA before your install CA, and the MSI framework will call the rollback CA if the install fails and rolls back.

Subject: Re: [WiX-users] atomic (un)install when using custom actions; Thanks Dave. Can you please elaborate? How can I author them to make my installation atomic. I have 3 custom actions - each installs a driver - creates some registry entries. I need to make sure that if the installation of any one driver fails then the rest of the drivers should also not be installed. Thanks. ----- Original Message ---- From: David Watson <dwat...@sdl.com> To: General discussion for Windows Installer XML toolset. <wix-users@lists.sourceforge.net> Sent: Mon, November 22, 2010 3:14:20 AM Subject: Re: [WiX-users] atomic (un)install when using custom actions; The windows installer is inherently transactional, your custom actions need to be too. Author them so that they install, uninstall and rollback correctly.

Is it possible to create checkpoints before installation and revert to it in case of an error during installation?

Is there a way to make sure that (un)install is atomic. I need to support both client as well as window's server versions.
