But when we wanted to upgrade the production server we encountered an issue.</p> <p>I was able to install efficy correctly. We were even able to reach the login page but after login this message appeared as a alert message : "class not registered, classid: {16d51579-a30b-4c8b-a276-0ff4dc41e755}"</p> <p>Efficy then succesfully logins but isn't able to retreive any data (same error message inside the crm).</p> <p>It seems that efficy tries to get a class id in the registry that isn't registered on the production server (seems to be jscript). It is registered on the dev server.</p> <p>Is this something that the efficy installer registers or is this more linked to the local server settings?</p> <p>Thank you for any information.</p> <p>Ken</p> Efficy Installation/Settings https://overflow.efficy.io/?qa=4631/installing-efficy-registered-classid-16d51579-0ff4dc41e755 Wed, 31 Jul 2019 15:17:51 +0000
