Surely I am not the only user who routinely re-locates the various TeXMF trees from their default locations with every new release of TeX Live.  I may be the only person to report the problem, but I am certain that I am not the only one to be inconvenienced by it.

We are not happy about it ourselves, but I see no simple remedy.

Without the necessary-and-sufficient three levels, my C:\TeX\Live\TeXMF\Local tree would be forced one level higher, to C:\TeX, whereas it in fact a part of TeX Live rather than TeX /qua/ TeX.

If you do have C:\TeX\Projects, then c:\TeX would normally already
exist, and you would not run into this.

It points to the perl of the installer, not the perl of the
installed system. Long ago, we tried setting environment variables
in windows from within perl, but that did not work right. But
setting them in the wrapper has the unfortunate consequence that
perl noes not see the original environment anymore.
