Software Deployment

Hello,

I have a following issue:

Before planning upgrade from version 8.0i patch 14 we had following deployment algorithm:

GPO assigns and makes installed Computer Based installation of McAfee 8.0i patch 14 with last DAT integrated.
Then next MSI assigned application delivers VSECFG_W.CAB to proper directory.
McAfee 8.0i takes settings from CAB and works perfectly.
--------------------
Current situation with McAfee 8.5i patch 1:

GPO assigns and makes installed Computer Based installation of McAfee 8.5i patch 1 with last DAT integrated.
Then next MSI assigned application delivers VSECFG_W.CAB (created by 8.5 version of Installation Designer) to proper directory.
McAfee 8.5i takes settings from the VSECFG_W.CAB and than applies all settings except AutoUpdate repository.
VSECFG_W.CAB - is 100% correct CAB, checked manually on installed product.

So, here is my conclusion regarding case:

By Default McAfee 8.5i has “Prevent repository settings modification” enabled.
So, when I apply my CAB all settings are resetting to assigned in the CAB , all except Repository.

The most interesting thing is, when I apply CAB second time it takes Auto Repository Settings. I guess that it happens only because my first CAB reset “Prevent repository settings modification” settings.
---------------------
Well, now I found few rational options for myself:

1st is to integrate final settings into administrative installation of McAfee 8.5i patch 1. But how???

2nd is to deploy McAfee without enabled “Prevent repository settings modification”. How??

3rd is to update Repository by some other way. But How????
Please help me to resolve this issue with McAfee 8.5i patch deployment.

I was suggested to use Protection Pilot or EPO agents to manage AutoUpdate tasks, but it is not a solution for me.

Thanks.
