Avast and 2008 SBSD server Edition NOTHING but problems NO clear support

From the Workstation installs to the server installs this has been one giant nightmare.

Issue 1 - after downloading multiple copies of setup_adnm_no_msde (sql server 2005 SP 3 is already running on the server) the self extract fails EVERY time so i can not even install it.

issue 2 - setup_av_net has the EXACT same problem

issue 3 - after installing the WS version on all the systems everything runs fine as long as it is an administrator. As soon as I log on with a domain account that has restricted privileges it asks for the license keys again but I can not enter them because I am not an administrator on the system. Any Ideas?

Any help would be appreciated.
