When trying to uninstall Oracle Client (from a Windows server) the standalone deinstall tool couldn’t remove the file “oci.dll”.
To remove it (without rebooting) I tried to manually delete the file. The error message indicated which Windows service I had to stop. (IE: First it was locked by “SQL Server” then when I’d stopped that “VMWare Tools”, then DCOM, then COM+.
After stopping all the locking services in order – I was able to delete the file.
Lastly I restarted all the services I’d stopped 😉
