Attempting to use deployment procedure's to install patch bundles on windows hosts, sometimes you run into issues with services keeping dll's (especially oci.dll) open.
Here's a trick to determining what service is keeping a specific dll open.
From a command prompt:
tasklist /m > tasks.txt
The look for the specified dll in tasks.txt and find the process. From there it should be somewhat obvious which service to shut down in order to get the patch to continue.
