I tried to install sql server 2005 6.4 bit on windows 2008 machine.
At first I installed it on C, realizing I should install it on another drive other than C.
So I uninstalled it from program features add /remove the program.
THen I reinstalled it. Everything went OK till last step. I got an error while doing reporting service installation:
An instance with the same name is already installed on this computer.
To proceed with SQL Server Setup, provide a unique instance name
It seems the reporting service is not totally uninstalled. Then I started my second try of uninstalling the whole program from remove programs, before uninstalling I stopped all the sql services and delete the reportserver application and application pool in IIS.
Then I restarted the server, I can still see the sql reporting service in windows service panel, although its status is stopped. Then I do another installation, I still get the above message.
It seems all other database services are intalled OK, but not for reporting service. It somehow stores the instance name. How can I remove the instance name for reporting service and do a successful reporting service install.
