Re: [WiX-users] Scheduling Install and Uninstall Custom Actions

[Wilson, P. <Phi...@in...>]

Component or feature conditions work much better in circumstances like this, a couple of examples that are by no means a complete list. 

1. Something breaks in your product that running the custom action would correct. You would ask the customer to go to Add/Remove Programs&Features and use Repair to fix it. The component reinstall would run the custom action and fix it. You don't have that option. 

2. The custom action is associated with a feature (or a component) that may or may not be installed depending on the features that are chosen. If that feature or component is not being installed, running the CA is pointless. The same is true if that feature is uninstalled.

Subject: Re: [WiX-users] Scheduling Install and Uninstall Custom Actions

I found a way by opening (via orca) my previous installer (made by Visual Studio 2010 basic msi). All the custom actions are using component conditions. I am not at all comfortable in this. So I am modified my current installer with following  CAs. Its working great.

<Custom Action="CA_SetBase_Install" Before="CA_Install">NOT Installed</Custom>
      <Custom Action="CA_Install" After="StartServices">NOT Installed AND NOT UPGRADINGPRODUCTCODE</Custom>

<Custom Action="CA_SetBase_UnInstall"
Before="CA_UnInstall">Installed</Custom>
      <Custom Action="CA_UnInstall"
After="MsiUnpublishAssemblies">Installed</Custom>

The CAs are working as desired. I want to ask about what is the diff between this approach and with component approach?

Also If I want to use rollback custom action then how to use it? Should Rollback be after StartServices and then Install CAs (coz this is how orca showed me, first rollback followed by install CA)?
