Group Policy - Issues deploying software packages through GPO

Question

Hello everyone,
I am having issues successfully deploying MSI packages through group policy.  I have set my computer account up in its own test OU in my domain, but yet the software will not deploy.  Example, I'm trying to deploy AVG Anti-Virus and make sure it
is installed on each and every PC in my domain.  As for the GPO, I set it up as an assigned package and pointed to the location of the package with the UNC file path (visible to both the DC and my computer that is part of the affected OU)
On the domain controller, I get these messages in application event logs:
Beginning a Windows Installer transaction: \\hs-dc2\software\avg\installavg.msi. Client Process Id: 9048.
Ending a Windows Installer transaction: \\hs-dc2\software\avg\installavg.msi. Client Process Id: 9048.
This shows up when I refresh GP on my computer.  I run gpresult /h GPReport.html and get the following message:
Software Installation failed due to the error listed below.
Fatal error during installation.
Additional information may have been logged. Review the Policy Events tab in the console or the application event log for events between
The software is in a share on the domain controller that is visible from my computer, and permissions are set where "Everyone" has read access.  I have tested the package on my computer and it installs
correctly if I do it manually, so it's a good package. 
I'm at a loss.  I am admitedly very new to GP management, but I'm pretty sure I have covered all my bases here.  I humbly ask for any and all help that you all can provide.
Thank you all very much, have a great weekend!

> Magnolia_Schools.exe
What's that???
> \\hs-dc2\software\avg\installavg.msi
> <file://\\hs-dc2\software\avg\installavg.msi> /qb addeploy=1
/qb ADDEPLOY=1
Uppercase matters (:
A bissle "Experience", a bissle GMV... Wenn meine Antwort hilfreich war, freue ich mich über eine Bewertung! If my answer was helpful, I'm glad about a rating!
I should have explained, my apologies.  The InstallAVG.msi is the package I have GP deploying.  it is a package that AVG wrote for us that goes in, uninstalls the two previous antivirus softwares we have on our network if it is present, and
then wraps it to run magnolia_schools.exe which installs the AV software.  I am uninstalling AVG now and will try reinstalling with
\\hs-dc2\software\avg\installavg.msi /qb ADDEPLOY=1 and report back.
also, the only logs I found that were around the time of the install attempt were such as these:
1: 2905 2: C:\windows\system32\appmgmt\MACHINE\{06ee0d46-cd5f-4216-a09f-2aeb573aa5ba}.aas
1: 2905 2: C:\windows\system32\appmgmt\MACHINE\{06ee0d46-cd5f-4216-a09f-2aeb573aa5ba}.aas
Does that tell you anything?
I will say this, if this means anything...now that AVG is installed, the event logs are changing from an error %%1603 to this:
Failed to apply changes to software installation settings. The installation of software deployed through Group Policy for this user has been delayed until the next logon because the changes must be applied before the user logon. The error was : %%1274
The removal of the assignment of application exe2msiSetupPackage from policy Install AVG failed. The error was : %%2
So it acts like it's at least seeing that the package is installed...and reacting differently, correct?
Thanks so much
