This laptop is office laptop which allows to install software using a "Thyocatic Administrator" option. The TurboTax 2018 software was installed successfully and I was able to begin my federal tax. When I try to install the California state tax patch, the updater gives are error message for failed update because of signature invalid. See attached screenshot (Updater_Error_CA_01192018.png) for details of the error. If I can manually download the software patch for CA, I can install it.
