SharePoint 2013: Dashboard Designer Not Showing Databases from Analysis Services - Resolution

Scenario
Currently only 1 WFE
PPS Service running on 1 Application Server
Unattended Service Account entered via the PPS Service Application
Same service account belongs to a Role in SSAS (2012) with Read permissions on a cube
BI Center Site Collection created


Problem
Launch Dashboard Designer
Create New Data Source from Analysis Services
Enter Analysis Services Server
Database drop-down shows Loading... but then nothing appears in drop-down list.


Resolution

1. Install  Microsoft® SQL Server® 2012 ADOMD.NET and Microsoft® Analysis Services OLE DB Provider for Microsoft® SQL Server® 2012 from the Microsoft® SQL Server® 2012 Feature Pack on the WFE and the server running the PPS Service
2. Install  Microsoft® SQL Server® 2008 R2 ADOMD.NET and Microsoft® Analysis Services OLE DB Provider for Microsoft® SQL Server® 2008 R2 from the Microsoft® SQL Server® 2008 R2 Feature Pack on the WFE and the server running the PPS Service
3. IISRESET on the WFE and the server running PPS.
4. Refresh the BI Center Site Collection
5. Launch Dashboard Designer again from BI Center Site Collection
6. Enter SSAS Server Name
7. Database drop-down loads with the databases now!

I wouldn't be suprised if I need to install ADOMD.NET on any new WFEs that I build out but I will update this post when that time comes.

UPDATE 5/28/2013: I built out a new WFE and suprisingly I did not have to install ADOMD.NET. Everything appears to be working correctly.
