The fix is in the first page of this thread, about two-thirds of the way down. I was having the same problem, and was actually told by Quickbooks support that my 113 gb wasn't enough space to run the installer. Did the 7-zip extract and everything installed just fine. I am continually amazed at how bad Quickbooks, and Quickbooks support is. I have to find a suitable replacement (which shouldn't be too difficult, given the problems with QB).
