When are policies being applied?

From Settings<Remote Management<Remote Control<Windows, I selected the pcAnywhere Plug-in for Windows - Install and Applied it to the following:

Start with all computers

 THEN exclude computers not in Computer list %COMPUTERNAME%

This should install the plug-in for the one PC, correct?  

I Saved the changes after ensuring that "Run once ASAP" was checked.

However, the device never got the plug-in (although the Symantec Management Agent, etc) were installed.  It is like the policy was never applied to the client.

I could manually install it from NSCap\bin\Win32\X86 through the command line, but I am just not sure when this policy is supposed to kick in.

Where can I find this information?
