Installation on "remote" server or local with wamp

Hello all,
I tried to install ProjeQtOr on a local server (wamp) or a remote server.
In both case I have the same issue, when I open the web app I get an empty page

In the console of the nav I see this error:
Erreur dans les liens source : request failed with status 404 URL de la ressource : [url]http://localhost/projeqtor/%3Canonymous%20code%3E[/url] URL du lien source : installHook.js.map
Have some idea for me.

Thank
Christian

Hello,
I founded a workaround by installing the version V12.0.4.
On my "local" server after installing the V12.0.4 I was able to update to the last release.
On my "remote" server I have installe the V12.0.4 without issue I still have to update.
