Failed to Install Update. Microsoft installer error 1603. Fatal error during installation.

I select TT because it always updates the program without error or effort beyond that of a simple wage earner.  Could someone offer a simple, emphasis on "simple"  on how to correct this.

This is my 8th year with TT.  I am really not more computer literate than I was in 2013.

I have disabled my virus programs with no correction.

expect random errors and issues until mid-January or later, since TurboTax is preliminary.

For some, the issues continue through tax season.

also, try right-clicking on the program and select "run as administrator"

here's a link to what Microsoft suggests for resolving the issue

Let me offer an important add here.

Just's for S&%$#'s and grins, I opened, and successfully updated, my 2020 TT program.

Is it fair in saying, it's is a TT matter, not a Microsoft matter?
