Windows 7 has a much more aggressive firewall built in. And the added security that is on by defualt can also get in the way.

On Windows7 machines make sure that you have network discovery enabled along with file and printer sharing.

Open port 18086 inbound to the agent machine. Port 18082, 135, 139 and 445 need to be open for incoming and outgoing connection to the Vipre server. Note that port 139 and 445 are enabled by default if file and printer sharing is enabled.

If the system meets all these requirement you should be able to push deploy with no problems. As for installing with the MSI package the only thing i could see getting in the way is the User Account Controls. That being the case if you log on with and administrator account and then right click the MSI and run as an administrator it should succeed.
