Zak H,
Thanks for the vb script! 
After reading your original post, I went ahead and wrote my own little "autoIt" script which imitates the manual process for displaying the SMA "Settings" window. Please see attached.
This script assumes that AeXAgentActivate.exe is the following path:
"C:\Program Files\Altiris\Altiris Agent\"
Thanks again for your efforts!
