This post does not answer the question. I never got that error message in at least 6 attempts to reinstall TT2019 Home and Business. I spent at least 4 hours on the phone with TT help and then spent hours on my own repeatedly trying to reinstall. At some point it is a waste of time to work with TT and I moved on. Fortunately I printed out the return before trying to e-file and just mailed the return.
