Javascript. I would ask them if they support a programmatic way to
obtain the version so you can safely automate it. A web debugger shows
that it retrieves the version information json from this URL (which of
course is subject to change since it's not documented):

From that data you can use jq to get the version information associated
with the latest ees_nt64.msi (which I assume is the one that would be
the most popular and one you want) that's in .files .installer. Doing
that depends on filtering for another URL which is subject to change:


$json_url =

$msi_url =

$tag = 'curl --fail --location -sS --proto =https "' . $json_url . '" | ' .
       'jq --raw-output ".files | .installer | first(.[] |select(.url |
endswith(\\"' . $msi_url . '\\"))) | .full_version"';

$tag = `$tag`;
!$? || die; # this only covers jq failure, there's no pipefail in cmd shell.

$tag =~ s/\r?\n$//;

print "tag $tag.\n";

It might be more reliable to download the msi instead and use
--time-cond / -z to download it when newer, see
