SitecoreRootCert do not found warning

SIF constantly throwing me below error while installing Sitecore Commerce 9.0.2.

According to warning, SitecoreRootCert is not available in cert:\LocalMachine\Root.
Open Manage Computer certificates and check SitecoreRootCert  is available or not.

I checked and it was not available in that location. what I did just moved SitecoreRootCert  to this location and error gone (missing SitecoreRootCert).
