roll out bugfixes without the need for Admin Rights!

Hello!

We have an existing, working AIR application developed for a client. the project is AS only and the air application needs to access to the harddisk as well as the web.

The client has outsourced the whole IT department and IT support to another company - therefore, whenever something needs to be done on the employees computers that require admin rights (like installing new software), an expensive process has to be started that goes through this IT support company.

the problem is, that if we release bugfixes or updates in functionality for our application through a new air file, the update process requires admin rights although the new version has the exact same access rights as the already installed one.

The client wants to drop our project if we can't come up with a solution of how we can rollout bugfixes and feature updates without the need of admin rights for the update.

How can we achieve this? Requiring Admin Rights for the first Installation is ok - but not for subsequent updates.
