[GNC] Norton Utilities prevent FQ installation

[Ruaraidh Sackville Hamilton]

Norton Utilities came with my new Windows 11 computer. GnuCash 4.13 is
working great and I've migrated my data from the old computer, but there's
one problem: the script supplied to install finance::quote has failed with
error message "failed to download perl install file". At the same time,
Norton Utilities gives a message that it blocked unauthorized access to
process data, so it looks like Norton is the culprit. Norton says it's just
an info message and no action is required (!)

I've tried:

   - disabling Norton's firewall
   - disabling Norton's antivirus checks for perl.msi
   - running the installation script as administrator.

None of these has helped.

Has anyone any suggestions for what to try next?
