Please help: OPatch fails (Following files are active : c:\oracle\ora11g\bin\oci.dll)

Hi All,  

I have the problem patching Oracle.

I get the error:  

Following files are active :

c:\oracle\ora11g\bin\oci.dll

ApplySession failed during prerequisite checks: Prerequisite check
"CheckActiveF

ilesAndExecutables" failed.

System intact, OPatch will not attempt to restore the system  

OPatch failed with error code = 74  

It seems that some other services are using this dll.

I read about this on the web and did some research and I found out that this oci.dll is beeing used by another services, and thus patch cannot be applied.

For example if I turned off manually servrices:

COM+ System Application

VMware Tools Service  

It did work. Sometimes it works without turning off these services.

But I also found that when I turn them off from the script that runs the patch they sometimes immediately come up again and my patch fails with the same error.  

Is there a solution to this problem? Can I find out what services I need to turn off before running the patch?  

Please help me and thanks in advance,  

Marcin
