hardware: Dell laptop
system type: 64-bit operating system, x64-based processor

operating system: Win 10 home
version: 1909
OS build: 18363.815

here's the message I get when starting:

Installing to: C:/program-files/texlive/2020
.\ls-R: The handle is invalid.

open(>C:/program-files/texlive/2020/tlpkg/texlive.tlpdb.tmp) failed:
Permission denied at
line 592, <STDIN> line 110.

I downloaded and ran the installer last week.
When I examined the logs from my test suite,
I noticed that my texmf-local\ls-R had not been updated.

I went to ...\2020\bin\win32
and ran hexhash.exe as administrator

here's the log:

Cannot open C:/program-files/texlive/texmf-local/ls-R to write.
Cannot open C:/program-files/texlive/2020/texmf-config/ls-R to write.
Cannot open C:/program-files/texlive/2020/texmf-var/ls-R to write.
Cannot open C:/program-files/texlive/2020/texmf-dist/ls-R to write.
texhash: Done.

note: the various 2020/*/ls-R files were correctly installed and have
correct date+time stamp.
the datestamp on texmf-local/ls-R has not changed from my last updates
earlier in the year.

what I have done:
* searched for ways to run an *.exe, as administrator
  : done; reran install

* enabled write permissions for my install folder:
  : unable to update read/write permissions for texmf-local

Q: what next?
