Windows XP Patch Deployment Fails

Windows XP Patch Deployment Fails

I am hoping someone can help me.  After my most recent patch to 10.0.91, I can't seem to deploy patches to any of my Windows XP machines.  I have no problem sending patches to my Windows 7 machines, only with the XP machines.  In the console it sits at ready to execute indefinitely and if I drill into the execution status it sits at yet to apply.  After I deploy the patches I want, if I go to that target XP machine, there is an error message on the screen as follows:

dcconfig.exe - Entry Point Not Found

The procedure entry point RegDeleteKeyExA could not be located in the dynamic link library ADVAPI32.dll.

I have tried removing and reinstalling the client agent without success.  What is the issue?
