Title: Re: [Wireshark-dev] Visual studio 2019 from choco

Oh.  A very old and unsupported (by MS) version of Win 10. See here for lifecycle info: https://support.microsoft.com/en-gb/help/13853/windows-lifecycle-fact-sheet

Indeed. It was a fresh install with no updates (due to network issues). I'm updating the system now: let's see if it suffices.
I'd add something in the docbook about using a supported version of windows, referencing your link.

In my experience it is significantly faster to download & install from scratch again from a recent ISO instead of going through all the update cycles to reach 1909... Those often take hours per cycle, and starting from 1511 probably means 1 or 2 days of patching to get there :-)
