I don't think you should install 2.0, then 3.5... but, honestly, I think that it's ONLY 2.0 that is causing it to work, and not 3.5...
I can confirm though, that in OMJ's latest, all you have to do is install SQLCE (and no, it won't work without it--meaning that a non-cooked installation of SQLCE DOES work.)

(for the Vogue) I haven't had any sort of error. Works great so far.
