Error while 'Install Extension to Design Studio'

Dear Experts,

When I try to load an SDK component from my local computer to the Design Studio, I got the following error message.

"Failed to discover all connectors.

RepositoryDiscoveryStrategy failed with an error

Failed to process repository contents

No repository found at ......"

My source file is in .zip format. And i am trying to install this .zip file.

I saw a similar problem in the forum and problem and the solution was "the bullet "Generate p2 repository" was unselected". But I couldn't even find this setting..

Can you please help?

Thank you in advance.
