OK, I may try that. But in the meantime I am performing a binary search on all TeX Lives from 2008 to date in order to find the year in which our
<i>Lexicon of Abbreviations & Ligatures in Greek Minuscule Hands</i> ceased to compile, and to facilitate this I now have a new hierarchy, C:\TeX\Legacy\<year>. If I move

OK, noted. Thank you.<br>

<pre wrap="">tlshell checks the registry whether it needs privilege escalation,

administrative permissions.
I guess that tlshell does not find the relevant registry entry,
otherwise you would have gotten a UAC prompt.
Maybe it was a search path problem, which should be fixed in the
latest upload.</pre>

OK, since this is purely for testing purposes I will probably delete everything under C:\TeX\Live\2019, re-rsynch, start again and report back.

Well, in the past I have always installed as Administrator, but that has led to so many problems that this year I installed as myself (an intentionally non-privileged user). I shall continue to use the latter option unless advised otherwise. But is there
really no debugging switch/aid/tool(s) for "tlshell" ?<br>
