Hi all, can anyone tell me an easy way to make the following chnages to my MSI file before I push it out via a Group Policy

What tool can i use thats free and easy to use to edit the file to make it do the following things:

1. I want the service to start automatically after its been installed (currently i have to do a reboot which i want to avoid)
2. edit the nxlog.conf (within the MSI) file to include it as part of the installation.

Ive tried using ORCA and some others with no sucess.

thanks
