Problem Installing Sage CRM 2019 R2

SUGGESTED

Hi all,

I have problem installing sage CRM on my laptop. After installation, this message pop up.

 

Then my colleague help me to configure the url rewriter and other thing and reinstall the application. the message box is gone but the web page still have error 404 not found.

the installation folder exist but there is no CRM and self-service web app created in IIS. I can confirm that my localhost working perfectly because all my other web is working fine.
