I never saw an error code when my TT Premier failed to complete the initial update process. I was also confident that it had nothing to do with my PC as it was only 2 months old and every other application on it ran perfectly. So I waited for about 10 days and then opened TT. It updated with no problem and I was able to complete my State & Federal taxes without any further issue.
Because you have an error code I would contact TT support for their help...
