Management Reporter - Couldn't retrieve the list of available databases: The connection attempt failed.

You get the error as seen below when trying to deploy the Management Reporter Data Mart under the "Database GP Connection Information" section.

"Couldn't retrieve the list of available databases: The connection attempt failed."

I experienced it with MR CU16 and other persons have experienced with older versions of MR. 

What to do:

To resolve the Dexterity Shared Components 12 needs to be installed. You can retrieve this from a GP2013R2 install file.

Once installed you can complete the MR Data Mart deployment.
