[SOLVED] Visual Studio 2017 installer fails to install KB2533623

Visual Studio 2017 installer fails to install KB2533623

I'm trying to install Visual Studio 2017 Community via web installer on my Windows 7 laptop and it fails, returning me this log:

dd_setup_..._error.log (translated into English from me, since it was in German)

Package "WindowsUpdates.KB2533623,version=15.0.26711.1,chip=x64" could not be installed.

KB2533623 is not installed at my Laptop, so I tried to install KB2533623 x64 by myself, but it's rejecting with the words "The update is not applicable to your computer".

After some research I found SCCMENTOR who is claiming KB2533623 is superseded by KB2758857, so I tried to uninstall KB2758857, first. There was an error that I could not uninstall all updates. Repeating the step in a local system CMD with wusa /uninstall /kb:2758857 returned 0x80070490. Microsoft suggests to scan the system for corrupt files with sfc /scannow, so I did. It found some errors and fixed them.

I repeated wusa /uninstall /kb:2758857 and it returned 0x80070bc9. Then I restarted and tried it another time and it gives me 0x80070490, again.

I'm not sure I'm on the right path, maybe KB2533623 is not the problem here. How can I fix the problem, so the Visual Studio installer is able to install KB2533623 that is required by so many components of the suite? If KB2533623 is really superseded by KB2758857, why the installer tries to install KB2533623 at all, if KB2758857 is already installed on my laptop?
