I have updated my reply. please check

Hi @Shaheena_Sheikh ,I checked the above code and I think it is because of the synchronous request in http.open('HEAD', url, false); If this value is false, the send() method does not return until the response is received and this might be the case parsys stops loading. If possible could you please ...

Hi @Engelmoer Could you please elaborate more and if possible add screenshots.

I followed this link for AEM desktop app installation. It is installed successfully but when I tried to run it, it is not responding. I also tried to run as administrator but still not getting any dialog for error or anything.
