Well actually support "suggested" that I rename the configuration file, delete all the extensions, reinstall them and try again. Which I did.....all 46 of them. Then I reinstalled, then put the serial numbers in, then put the pages.js patch in, then put the ecart patch in and started again. Well the "wizard" ran. Everything worked except at the "manage orders" steps where it couldn't find the correct ecart object. I had an earlier one which I had deleted and built a different one. The new one was used on the first part of the wizard but it pickup up the name of the old one and of course no connection for the data. I cancelled the wizard. Deleted everything. Tired again. You guessed it. The same js error was back. I reapeated the whole process yet another time. Same result. This time I just told the "wizard" that I'd manage stock myself.
Seems like the goal of a "wizard" should be to save time or accomplish something really difficult. I AM TOTALLY UNDERWHELMED BY THIS WIZARD. I wasted a lot of time to accomplish very little. My recommendation is that is should be deleted from the product until it has made it out of beta. A good manual would be a LOT better and would have saved me a lot of time.
