No tray icon for CIS on Windows XP


After a CIS update (on Windows XP) I noticed that I can’t get its tray icon to show up.
Current CIS Version: 7.0.317799.4142

Here is the list for what I have tried so far:

Active related processes:

What happens when I try to launch cistray.exe manually:
cistray.exe appears on the the process list but vanishes almost instantly

However running cis.exe will produce a window which is really not a good solution since it does not produce the pop-up windows informing you whether an application has been sandboxed or firewalled (one has to know his way in finding what he’s looking for among: Unrecognised files/Sandboxed Apps).

I would appreciate any guidance on how to debug or investigate this situation.
