Just realized that the issue might have been caused by a small change in the installer I made yesterday, will probably work now if you try again.
If not:
If you didn’t keep your web installer, you can get one from the link below.
If the issue is caused by your antivirus, that might not work either though. If you use something else than Defender, really just get rid of it. There is zero reason to use some extra annoying third party AV since many, many years.
