Patching Questions

Could someone please explain how I create an admin image andpatch that image to the latest release of Solidworks. This is whatI have tried so far:

Created admin image from DVD of 2008 SP0 using msiexec /a
Now, I want an admin image of 2008 SP3. It seems I can onlydownload that from the internet and when I try to patch my DVDadmin image using the Solidworks installer I get an error saying itcannot be patched or cannot find some compatible version.

So I thought maybe I should download both SP0 and SP3 from thesite, which I did last night. Now, when I try to create a one stepinstaller image from the SP0 I just downloaded, the stupid programsays it cannot find disk1 and wants to go back to the internet toget missing software. Wasn't everything downloaded with SP0?

I have to say that Solidworks really made this more difficult thanit has to be.

Any help would be appreciated because I am thoroughlyconfused.SolidworksAdministration
