When you try to uninstall Microsoft SQL Server 2008 Reporting Services from the server, you may receive the following error message:
Note Drive_Letter refers to the disc drive into which the SQL Server installation media is inserted.
An error has occurred:
Access to the path 'Drive_Letter:\WINDOWS\system32\perf-ReportServer-rsctr.dll' is denied.
This problem occurs when another process or application, such as Performance Monitor, may be running and using the Report Server performance counter (perf-ReportServer-rsctr.dll).
To resolve this issue, close or stop any process or application that may be using the Report Server performance counter, and then try to uninstall Report Server.
