[texhax] Bug in TexLive installer

[hz hzmonte]

I just downloaded the install-tl-windows.exe for Windows from https://www.tug.org/texlive/acquire-netinstall.html for my Win XP.  It has been a big hassle to install it.  I think at least part of the problems is that an outdated version of perl - perl522.dll (and maybe other files as well) was included in \install-tl-20170116\tlpkg\tlperl\bin.  The installer looked for perl524.dll !
