[Bug] TeX Live Installer removing User PATH entries on Windows 10

[Norbert Preining]

Hi Laurin,

thanks for the report, interesting that nobody has reported this since
ages.

Also, from the code, it doesn't seem like this should happen.

Could you do the following:
* get a current installer
* unpack it
* change tlpkg/TeXLive/TLWinGoo.pm as follows:

diff --git a/Master/tlpkg/TeXLive/TLWinGoo.pm b/Master/tlpkg/TeXLive/TLWinGoo.pm
index e7076aea7ee..9251190c6c9 100644

     setenv_reg("Path", join(';', @newpath), $mode);
   } else {
     debug("TLWinGoo: adjust_reg_path_for_texlive: calling unsetenv_reg in $mode\n");


That is:
- add one debug line (first line with + starting, but don't include the
  + itself
- change the debug line (from - to +)

* Then run the installer with 
	./install-tl -v ...

That should output a lot of things, but also the above 
	TLWinGoo: adjust_reg_path.....
with the old path and the new path.

You can also just send me the full debug output.

Thanks

Norbert
