I was wondering if anyone would be able to tell me how to turn the Prism Client (we are using Prism Deploy Client 6.01) into a .msi package?

I need to deploy the package via group policy in Active Directory and automatically have the target computer subscribe to a channel server to push out several different Prism packages.

We have tried to package the Client files and the subscription file as a .msi but, when the package is run, the client installs but the prismxl service does not launch and the computer does not subscribe to a channel. If we manually install the subscription file everything is fine.

If you install the Client via a MSI (converted from a Package), then the machine is going to require a reboot before the Client will begin polling.  If you wish to install the Client via a Group Policy, there is a Knowledge Base article that describes the process.  It can be found here:
