MetaLAN Server 2.6.1.238 setup takes up to 5 minutes to install the network scan service on Windows Server 2012 R2.  The installer then completes without error.


The reason for the delay is not known and does not happen on the non R2 version of Server 2012. 


Hammer Software is investigating the issue and will release a fix if the root cause can be identified and corrected.


Workaround: Wait for up to 5 minutes while the service installs.
