Installation Error

Hi,
I am not able to install the plugin. Any help would be appreciated.

I get the following error:

Fatal error: Uncaught RuntimeException: Unable to create the key in D:\home\site\wwwroot\wp-content\plugins\perfecty-push-notifications\vendor\web-token\jwt-core\Util\ECKey.php:148 Stack trace: #0 D:\home\site\wwwroot\wp-content\plugins\perfecty-push-notifications\vendor\web-token\jwt-core\Util\ECKey.php(110): Jose\Component\Core\Util\ECKey::createECKeyUsingOpenSSL('P-256') #1 D:\home\site\wwwroot\wp-content\plugins\perfecty-push-notifications\vendor\web-token\jwt-key-mgmt\JWKFactory.php(75): Jose\Component\Core\Util\ECKey::createECKey('P-256', Array) #2 D:\home\site\wwwroot\wp-content\plugins\perfecty-push-notifications\vendor\minishlink\web-push\src\VAPID.php(169): Jose\Component\KeyManagement\JWKFactory::createECKey('P-256') #3 D:\home\site\wwwroot\wp-content\plugins\perfecty-push-notifications\lib\class-perfecty-push-lib-push-server.php(80): Minishlink\WebPush\VAPID::createVapidKeys() #4 D:\home\site\wwwroot\wp-content\plugins\perfecty-push-notifications\includes\class-perfecty-push-activator.php(42): Perfecty_Push_Li in D:\home\site\wwwroot\wp-content\plugins\perfecty-push-notifications\vendor\web-token\jwt-core\Util\ECKey.php on line 148
