I am trying to add datadog APM to my php app which is running on IIS, but while testing the added executables and running php -m I am getting the error PHP Startup: **Unable to load dynamic library ‘ddtrace’ (tried: C:PHP7extddtrace (The specified module could not be found.), **C:PHP7extphp_ddtrac

I have tried upgrading the php version to 8.
I checked the ddtrace file permission and it is having all rights.
I tried adding the path to this dll file in the environment variable.

My expectation is that php should load dynamic library ‘ddtrace’
