If you don’t require the install to run in user context (i.e. don’t need access to HKEY_CURRENT_USER registry hive), but have some UI displayed to the user, then you can use the following override commands to give the logged on user system authority for the specific wait command:
override wait
runas=localuser
user={name of logged on user}
password=system
If you do need user context, then you can use any arbitrary user that you have the password for, and direct the UI to the current user via targetuser. The following example runs the command as the user DOMAIN\user1, giving it admin authority, and shows any UI from the command to the currently logged on user:
override wait
runas=localuser
user=DOMAIN\user1
password=required
asadmin=interactive
targetuser={name of logged on user}
