If an eHealth installation fails on a Windows server, it is often necessary to completely remove the files partially installed on the server before making another attempt. When removing the Oracle directory, users may encounter errors that one or more DLL files are in use and cannot be deleted.
ENVIRONMENT: This could affect any version of eHealth on the Windows platform
To determine what process is locking the DLL, run the following command from a command line interface:
tasklist /M moduleName.dll
The name of the service or process that is using that DLL file will be displayed. You can then end the process using the Services control panel, the Task Manager, or the kill command.
c:\>tasklist /M ora32.dll
Image Name PID Modules
thisProg.exe 1234 ora32.dll
