Unattended access without permanent install

[projecttoday]

I'm trying to access my work computer from home.

I'm able to access the work computer from home if I go home and connect and then drive back to the office (20 miles) and click "allow connection" and then drive back home (20 miles).  If I try to set up unattended access on the work computer, it won't let me because teamview isn't permanently installed. They do not allow me to install anything on my work computer.  Is there any way around this (without another person)?

Or can anyone recommend another program for this?
