Install Design Studio Extension on SAP BO BI Platform

Hi Experts,

I am using :

• SAP BO BI Platform 4.1 SP5 + Design Studio 1.5 add-on for BI Platform.
• Design Studio 1.5 64 bit Client.

I have installed two extensions from:

• Tools > Install Extension to Design Studio
• Tools > Platform Extensions

The extension is working fine locally. But when I view the same dashboard from BI Launchpad, I am getting error below:

Am I missing anything ?
