If when installing WorkflowGen Windows Services, after running “DRIVE:\Program Files\Advantys\WorkflowGen\Services\bin\winsvc-install.cmd”, you receive the following error message:

Unable to create an instance of the Advantys.Directories.Win.Services.SynchronizationService.SynchronizationServiceInstaller installer type.

it is because the installation must be performed with administrator privileges. Install it again by right-clicking “winsvc-install.cmd” and choosing Run as administrator.
