Piwik installation issues

Hi

I am trying to install piwik on my OHS server (Oracle HTTP Server). My machine satisfies the minimum system requirements as mentioned in Piwik Requirements - Analytics Platform - Matomo

I am following the steps provided in Installing Piwik - Analytics Platform - Matomo

However, I am unable to see the ‘Welcome Screen’ from where I can proceed ahead with the Piwik installation.
I am only able to see the piwik.js on the browser when I login on the url /analytics/piwik/piwik.js but I get an
"HTTP 403
Forbidden You are not authorized to access the requested resource."

when I login on /analytics/piwik/

Kindly help me resolve this issue.

Thanks,
Varun
