error 42016 running 2018 TurboTax Windows on Window 11 machine
Installed "w_turbotax_1040_prm_[phone number removed].exe"
Upon running I get the following errors as it trying to update.
1) Dialog 1 - Could not connect to the update site (Error 42016: Unexpected content received)
2) Dialog 2 - Internet Connection Error - unknown error 42016
I can not proceed. I have it installed "w_turbotax_1040_prm_[phone number removed].exe" on my older Windows 10 machine, same problem.
Hoping there is a way to get passed this since the updater is not required for sure on my older machine. The newer machine definitely since a new install.
Thank you,
Dan
