Using the Administrator account, when I try to install TurboTax 2019, I get error code 65535 and the installation fails. I have Windows 10 build 2004.
Are you installing from a CD or a downloaded installation file?
Did you only recently upgrade to Windows 10 v 2004? If so, I'm wondering if Windows update is still installing in the background or some installer process already running. See this FAQ:
