Sql-server – SQL Server 2017 installation unauthorized error

authorizationinstallationsql serversql-server-2017

I'm getting the below errors while installing SQL Server on a Windows machine.
I'm using my admin account which has permissions (I’m in Administrations group. Verified here -> Computer management -> Groups)

Does it ring any bells based on the below errors to anyone? Are there any known workarounds. Spent a day without any good solutions. This is a fresh installation btw. The worst part is I can't even uninstall it as it complains about the same unauthorized error.

Let's get the obvious one out of the way ...

Did you run the installer program "as Administrator" ?

Just being in the "Administrators" Group stopped being enough to "break" your machine somewhere around Windows Vista!

To get into an "elevated" security context, wherein you can make changes to your machine, you must pass through the User Account Control (U.A.C.) "Challenge" by running the installer program "as Administrator".
