For everything but Lotus Notes and Microsoft Outlook I publish the exe file.

The reason for Notes being published as a script is that we are mid way through a migration from one release to another and until we publish a script which checks that the client is up to the latest release.

Outlook is published via a script because my predecessor initially installed Office without using a Custom install wizard to create Outlook profiles on Outlook start and I haven't had a chance to set this right as yet! Its one of many things to tackle in the New Year!
