When I am trying to import CRM Labs Solutions Healthcare Template (http://dynamics.pinpoint.microsoft.com/en-us/applications/healthcare-template-for-microsoft-dynamics-crm-12884940944)
in Microsoft Dynamics CRM Online I get an error :
The solution file is invalid. The compressed file must contain the following files at its root: solution.xml, customizations.xml and content_types.xml. Customization files exported from previous version of microsoft dynamics crm are not supported.
Did you by chance install the zip file instead of the cab file? I believe the cab file that you downloaded from pinpoint can be directly installed.
