When installing DigaTransfer 4 (Broker/Worker/Analyzer) on a Windows Server 2008 R2 Operating System please ensure that you add the following server feature:
Server Manager > Add Features > .NET Framework 3.5.1 Features > .NET Framework 3.5.1
Older Operating Systems must be updated by manually installation of .NET Framework 3.5 (SP 1)
Please install all available security patches afterwards. This will include the patches for older .NET Frameworks.
If .NET Framework is not installed correctly DigaTransfer Worker 4.x could be started but it won't work properly and shutdown of the Worker application will result with application hang popup.
