Is `zendframework/zend-modulemanager` in your `composer.lock` and in `vendor/zendframework` ?

- Yes, it is.

Did you include ` __DIR__. '/vendor/autoload.php` somewhere at the startup of your application?

- Yes, i did create the file as admin.php and previously tried with include ` __DIR__. '/vendor/autoload.php` - but was getting errors as below :

**Warning** : include(C:\xampp\htdocs\project\module\Admin/…/vendor/autoload.php): failed to open stream: No such file or directory in **C:\xampp\htdocs\project\module\Admin\admin.php** on line **18**

**Warning** : include(): Failed opening ‘C:\xampp\htdocs\project\module\Admin/…/vendor/autoload.php’ for inclusion (include\_path=‘C:\xampp\php\PEAR’) in **C:\xampp\htdocs\project\module\Admin\admin.php** on line **18**

Not sure, how to go through…
