HTTP protocol error. 403 Proxy Unacknowledged

Mar 28, 2011
I just purchased version 13.0. When I try to register it I get "HTTP protocol error. 403 Proxy Unacknowledged." Any idea how I can resolve this?

Your proxy server is blocking Take Command's access to the registration server. You can either configure the proxy server to allow Take Command access, or you can go to OPTION / Internet (in TCC) and enter your proxy information.

If you're unable to do either of those, you can email [email protected] and request a manual activation key. (The disadvantage to the manual keys is they do not support autoupdate.)
