Why don't you run it as a scheduled task as a silent install?

Can you run a scheduled task as the user who is logged in (and set this up remotely)??? These apps needs to install under the users context because of HKCU settings and not the admin or system context. I have not found a way to do this using jt.exe or At.
If you know a way to run a scheduled task as the user (remotely) please post because this would be very useful for me.
