Do all WUs error out? In my experience CreateProcess() failures tend to either be permission/access issues or another program is tying up the executable.. like a virus scan or something.

If this was based on Android exposure, please do -not- confuse the way those device work, or don't work, with that of a PC. An entirely different beast.

The becay pointer is a probable cause... when there's much traffic, security software has been obstructive. Note that each time a new application version first arrives, the AV software and the like checks out, and if on auto-reject without response from user [and to remember the decision], that's where it goes, to the blocked box].

But, with the sparse info, only mention of 8 pages of fails, no context of success rate, it's hard to assess and becomes a wet finger in the air.

You are right :) Thanks!
