[tex-live] Bug in TexLive installer

[hz hzmonte]

Typo correction of the prev message: "unable" should be "unstable".
Also, I initially clicked on the install-tl-windows.exe file to do full/custom installation but failed.   It gave me a  "wget.exe has encountered a problem" error and the last part of the installation window showed "Extract: install-tl-20170116\inst_mod.bat  Starting the main installer:  ..."  So I unpacked the files instead and still got errors as mentioned in the prev message.
