I assume the 'yes' refers to my last question :) Hmm, but if the installation deferred action runs after installing the files, won't its rollback action run before removing the files? The index updater would run with the same result (storing pluginB in the index) and *then* pluginB.dll would be deleted... I guess I have to try it to understand the ordering better. -- Nicolás ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
