Problem: Installing Visual Composer

Hy,

I get the following error when trying to install Visual Composer:

Error: Unresolved dependencies found for the following SDAs:

1.: development component 'vc_client'/'sap.com'/'SAP AG'/'7.0010.20061023104739.0000'

dependency:

name: 'vc_ds_service'

Could someone tell me what is exactly the problem?

Thanks.
