Software Deployment

I am currently using ManagaEngine: Desktop Central 7 to deploy/update the following software on machines running either windows xp pro or windows 7:

1. Adobe Reader

2. Shockwave

3. Flash

4. Java


The program basically works by sending cmd commands to the remote machines telling them to install the updates from a network share, typically including the silent switch.


My problem is this:

A lot of times the user has a previous version of the software already, or the software is currently running, which causes the silent installation to error.


I believe the program allows you to run a script before the deployment, so I need a script that will:

1. Check if the program is running and if it is, end it.

2. Check if any versions of the software are already installed and if they are, silently uninstall them first.



Any help would be greatly appreciated!

Thanks.
