When you mention you copied the 3 Azure extension files, I'm assuming you're either looking at a package that's not for architect or perhaps they're just Ext.ux.* classes - that's not going to work in Architect.

If you already know this, my apologies - but there has been some confusion in the past.

Architect extensions aren't the same thing as packages. You need to install them into Architect, and they'll be downloadable in the form of a *.aux file.
