Answer 1

Not trying to bring up anything old. How I fixed the problem was to uninstall the installer completely. You can do this by removing everything(in the list of installed items), and it'll prompt you to remove the installer. Then you can reinstall; when you reinstall it'll first ask to "update" the installer or something similar. Click Yes. Afterward, you can install it like normal.

1. Uninstall all MySQL items, including the installer
2. Reinstall the launcher, but click yes on updates
3. Should work

Answer 2

I got the same problem today after re-installing windows 10 and then trying to install everything I needed for work.

What helped for me was accepting the (weirdly formulated) 'update installer' prompt with 'yes'. This prompt appeared right after opening/running the installer. The first time I ignored it with 'no' because I was under the impression that downloading an installer would get me the newest version. Then I got this error. Even after retrying three times (also after uninstalling). When I tried installing again and accepted the 'update installer' prompt the problem was gone.

Accepting to update installer in the beginning worked for me when installing mysql-installer-web-community-8.0.15.0.msi
