I have take a look at what exactly happens when publishing a multi-file update on Server 2008 and Server 2012. In both case, WPP detect correctly the additionnal files, but Wsus API seem ignore them when publishing on Server 2012. On Server 2003, the update's CAB is well formed.
I have modified the way WPP handle multi-file updates, so that now all files are in the same folder instead having the principal file in a folder and additionnal files in another.
This is not, in my opinion, the logic way to proceed. But Wsus 4.0 seems to change the process of publishing multi-file update.
I need to test the new release on Server 2003, 2008 and 2012, to ensure that this correction didn't brings other bugs.
I hope I can achieve this tomorrow.
