I installed SQL server 2008R2 on my computer, However, for some unknown reason the Analysis service has become corrupt. So I just removed the Analysis service. Now I want to install it again. As soon as the installation procedure starts, I get the following error:
TITLE: SQL Server Setup failure. SQL Server Setup has encountered the following error: The specified instance name is already used by an existing SQL Server instance. To continue, specify a unique instance name for this SQL Server installation. Error code 0x84B40000.
