MSDE setup for Sql Server-based Analysis - cannot find install media

Hi all, I'm trying to setup Analysis using SQL Server but falling at the first hurdle. All my searching indicates the necessary software (MSDE) can be found in installation 'Additional Components', so I have downloaded "HPE LoadRunner 12.55 Community Edition" but I cannot see anything that looks like MSDE in there. Ilooked again & found & downloaded "HPELR_1255_Community_Edition_Additional_Components.zip", but same result. I have an older 12.50 download, nothing there either.

This should be easy - can someone point me in the right direction, please? Do I have to go back to older release?

thanks

Steve
