Hi capsu_uter, what you need is not a Deployment Task but an Update Task; once you have patch 2 in your repository (only patch 2, not VSE880lmlrp2) you can set your update task selecting VirusScan 8.8 uncer patch category
We have worked with McAfee Team and tried the way you said. But it did not work also.
We already tried to upgrade patch 2 by setting the update task selecting VSE 8.8 under pact category, but in vain.
I have attached the logs above for your reference.
We also submitted MER Tool Logs to McAfee Team.
Do you have .msp in your MIME types?
If you don't it will look like the patch install but actualy it never installs then you will have to remove some registry entries and execute an update task after adding the MIME type.
