This is probably more of it works different than a problem.
I had to move a Mas90 install from one laptop to another and even though both were v4.4, I could not follow the standard Move instructions of re-installing over the copied folder.
I had to do a complete v4.4 install including the Service Pack and then do a parallel migration of v4.4 to v4.4.
Or I could just be losing my mind.
