Service pack upgrade (Admin image)

Ok, I've got 2008 setup as an admin image. I install sp1.1,then update the image to sp2.0 and the clients update. But if youlook in Add/Remove programs on the client, it lists both 1.1 and2.0. I can only imagine that this will get worse as time goesin.....sp3.0, sp3.1, sp4.0, etc...

There are not two installs, just one so I tried removingSolidWorks, edrawings, dwgeditor, etc. Now I'm still left with bothsp1.1 and sp2.0. Well, I finally figured out that these entriesthat are left are for the install manager.....apparently both sp1.1and sp2.0 are left behind.

Now you can manually remove them from Add/Remove programs but Ican't for the life of me figure out how to silently remove them.There's no command switch list anywhere for "sldim.exe". Theregistry shows "/remove" but all it does is bring up InstallManager and tells you that no products are installed, though if youhit "Remove" it will then remove the install manager.

This installation manager needs to cleanup after itself better whenupgrading from one service pack to another.
