Use msiexec to remotely install an .msi file accross the network

Question

I'm trying to install an .msi file via group policy but am not having any success. How can I install an .msi file onto computers accross the network using the msiexec command instead of psexec? I'm using this scriptwith psiexec below to no avail,
I'm running the script as domain admin and the everyone, domain users and domain computer security groups all have ntfs full control permissions to the share folder and co-owner permissions
to the share. I can also install the package manually and reach the share from the computer using
\\servername\share
C:\Users\hrice>psexec \\10.1.20.164 -u abc\admin -p password!! msiexec /i "\\abc-fs\comp
any\IT\Shared\Adobe Flash Player\install_flash_player_11_active_x.msi\install_flash_play
er_active_x.msi" /qn
PsExec v1.98 - Execute processes remotely

Doesn't matter, you wanted to use group policy to assign the MSI over the network anyways, right.

* 1 - Click the Windows "Start" button and type "gpedit.msc" and press "Enter." This is the shortcut command to open the group policy editor.
* 2 - Double-click the "Computer Configuration" icon to expand some options. Click "Software Settings." Right-click "Software Configuration" and select "New Package" to open a "New Package" wizard.
* 3 - Click the "Open" button and point to the location of your MSI file. This can be on a network drive, or on the network server. Click "Open" to save the location.
* 4 - Click the "Assigned" option and click "OK." The "Assigned" option assigns it to network users. You can disable the package in the future by editing the group policy properties and removing this check box.
* 5 - Click "OK" to save your package. The new package is shown in the details pane and it takes effect the next time your users log in to the network.
