problem installing Sql Server SP4

Hello,
I am getting the following error message when installing sp4 on a 2nd
instance of sql server 2k on a win2003 server
"Specified file cannot be opened as write. Ensure file is not is use and
restart setup
C:\Program Files\Sql Server\80\Shared\msxmlsql.dll"
I rebooted the server and still get the same error message. When I click OK
on the error message sp4 setup shuts down. Any suggestions appreciated what
I can do to get around this problem.
Thanks,
RichI fixed the problem. Turns out that I had a 2nd instance (a new instance of
sql server running). I had to shut down the first instance. THat was what
was using the file below. I was then able to lnstall sp4.
