You are unable to install the SharePoint DLP Solution and need to know which user permissions are required for installation.

The user performing the installation of the SharePoint solution must have the following roles:

    Farm Administrator

    Whether logged in user can install and deploy SP solutions
    Whether the SP Administration service is started
    Whether the SP timer service is started
