Hi Chen,
I had to use the Sysinternal Process Explorer to view which process holds the file LIBEAY32.DLL in use, it wasn't shown in the resource managers' diskactivity.
I finally found the culprit! It appears that the VNC SSL Proxy Service holds the file open and it isn't stopped by the agent update package. When manually stopping VNC SSL Proxy Service and then applying the agent update it works fine.
So I've created a settings task which first disbales the VNC SSL Proxy Service. Then I send the update agent task. The update then completes successfully.
Looks like an issue with the agent update package which doesn't stop or disable the VNC SSL Proxy Service prior to replacing the files including LIBEAY32.DLL.
Frank.
