It's quite time consuming though.  I have problems with file
permissions quite often at work and asked our IT department for help.

I don't have access to a Windows machine right now and dialog boxes on
the machine at work are in German.  Maybe someone with an English
version could provide a more exact answer.

Windows uses access control lists instead of Unix-like file
permissions.  If you create a new subdirectory, this directory
inherits the permissions from its parent directory.

If something is wrong, go to a parent directory in the Exploder, for
instance 'c:/texlive/'.  Then right-click on the problematic
directory, for instance '2020' or 'texmf-local' and select
'properties'.  Select the 'security' tab.  Check whether the
permissions of this directory are correct.  This is very important.
If you are not sure, compare these settings with those of other

There is a button 'Erweitert' on a German Windows, maybe 'Extended' or
similar in English.  If you click on this button you'll see a checkbox
at the bottom which, when checked, makes all subdirectories to inherit
the permissions of the current directory.  This takes a while because
the whole tree has to be scanned but is *much* faster than copying
files around.

Maybe someone with an English Windows can provide a better
explanation with exact wordings.
