Error 0x80070bc2 during installation KB4074588

To get the option, you have to access your computer with a user account that has admin privileges. To check this

Start....

Settings....

Search in settings window "find a setting" box: user

Select: your account picture and profile settings.

Account name must have Administrator under it.

Edited: On my system, if I select CMD with an account that does not have Admin privileges, on right mouse click I get the option to run as administrator, and I am prompted to enter an account and password for an admin account.  If you are not getting the option at all, I don't know why.

when I right click the command prompt I don't get the option to run as administrator!  What am I doing wrong?

When I ran the SC command in the Powershell, instead of the command prompt, I got the same error message.

When you run the command, the window you are in should be titled "Administrator: Command Prompt".

It should not be labeled as Powershell. You may want to check this.

Good luck.

If you are currently experiencing the 0x80070bc2 error while attempting to install KB4074588, please try this:

1. In the search box on the taskbar, type cmd.
2. Right-click Command Prompt in the search results and select Run as administrator.  (Select Yes, when prompted by the User Account Control.)
3. In the Administrator: Command Prompt window, type the following command and press Enter:

SC config trustedinstaller start=auto 4. Restart the PC.

In some cases, a second restart may be required. If you look under Settings > Update & security and you see the message Status: Awaiting restart, restart the PC a second time to complete the installation.

I got the message that the specified service does not exist as an installed service.

This is what I get:
