Hey, here’s Martin again 🙂

When you use System Center Update Publisher together with System Center Configuration Manager (even 2007 or 2012), you will get to the Trouble, that when multiple Users want use SCUP, they all got their own Database in their Profile Directory.  This means, that other users don’t see, which Updates are already been published by another user.

There is a possibility to share the database:
Modify the Scup2011.exe.config file, which resides inside the SCUP Installation Folder the following way:
Original:
<applicationSettings>
  <Scup.Properties.Settings>
    <setting name="SSCEDataFile" serializeAs="String">
      <value />
    </setting>
  </Scup.Properties.Settings>
</applicationSettings>

To this, where the Folder should be your designated place for the SCUP DB:
<applicationSettings>
  <Scup.Properties.Settings>
    <setting name="SSCEDataFile" serializeAs="String">
      <value>D:\Program Files\SCUP2011\Database\scupdb.sdf</value>
    </setting>
  </Scup.Properties.Settings>
</applicationSettings>

Hope this helps.
