Cannot install in TB 60.7.2 (32 bits) on windows

Hi,
I cannot install this valuable add-on in Thunderbird 60.7.2 (32 bits) on windows. I am trying to install it on new fresh Thunderbird install. A message is saying the add-on is not compatible with TB 60.7.2
The Thunderbird error console is stating:

1561994393621 addons.xpi WARN Add-on {03EF8A6E-C972-488f-92FA-98ABC2C9F8B9} is not compatible with application version.1561994393651 addons.update-checker WARN Request failed: https://versioncheck.addons.thunderbird.net/update/VersionCheck.php?reqVersion=2&id={03EF8A6E-C972-488f-92FA-98ABC2C9F8B9}&version=1.3&maxAppVersion=60.0&status=userEnabled,incompatible&appID={3550f703-e582-4d05-9a08-453d09bdfdc6}&appVersion=60.7.2&appOS=WINNT&appABI=x86-msvc&locale=fr&currentAppVersion=60.7.2&updateType=49&compatMode=strict - [Exception...

I guess there were some changes in TB 60 regarding add-on compatibility but on Add-ons Thunderbird page the add-on is stated as to "Works with Thunderbird 45.0 - 61.*"

It is maybe linked to issue #64 ?

Also not working for me after an update to 60.7.2 (it was on earlier release). No obvious error, but the search entry box no longer shows up.

The beta xpi (beta/gmailui-1.4-tb.xpi) works for me with TB 60.7.2 (32b) in Windows.

Beta does not work neither. The message is a bit different saying that the file seems corrupted... tried several download, same effect.
the console error:
