To deploy the Admin tools with the SWV agent the only way I could get it to work was to run the install twice, once to install the agent and then again straight afterwards to install the Admin tools. Using DS 6.9 "Distribute Software" task the additional Windows Installer command line switches are :
REBOOT=ReallySuppress PRODUCT_KEY=xxxxx-xxxxx-xxxxx-xxxxx ALTIRIS_NS=1 ADDLOCAL=Complete,SDK,SVS_Admin,FSLRDR,Altiris_NS /l*v SWVv615126.log
