If you work with MDX, using MDX Studio is a must, but it has not been updated for years. But community is great and Ihor Bobak has been able to apply two fixes: performance counters work with named instance and there is a single version regardless of the client libraries, so you have only one executable working with all available versions of Analysis Services (2005, 2008, 2008 R2, 2012, and 2014).
You can download this refreshed version of MDX Studio from http://sql.bi/mdxstudio (we also have a nice shortened path now!).
