Update Adobe AIR help content without necessity of installation for users???

Hello there,

I want to make our manuals available as Adobe AIR help applications. Unfortunately for our users it is not possible to regularly install these applications. Therefore I decided to generate a help viewer as AIR file and help content as RHA file ("help content only" ssl option). So admins only once have to install an initial AIR file. Afterwards users are able to replace help content to update help files.

I proceeded in a similar way as described here:

In principle this is a good solution - but here is my problem:

Help content itself already consists of different projects (merged projects). Merged projects unfortunately cannot be generated with "help content only" ssl option.

Anyone has got an idea how to satisfy all my conditions:

- Customers only once have to install an AIR file

- Afterwards help content can be updated by replacing files (without installation)

- Help content itself contains merged projects .

Generate different outputs (RHA files) for the merged projects is not a possibility. The merged projects with regard to content belong to ONE single manual - I'm not talking about different manuals. So users should be able to search the whole manual and so on ...).

Thank you so much in anticipation!
