[GNC] Data storage location for GnuCash 4.12

[flieger<at>sonic.net]

I just updated from 3.8 to 4.12  In the process, the install indicated it would delete the existing GnuCash - which is 
ok as I had full backups.  After the install, the data is being stored in the same directory into which I downloaded 
the installer, not to the directory indicated in the About dialog or the directory which was used by the previous 
version.  I have been unable to change the data storage directory and have even been unable to locate it in the 
registry (using Win 8.1).  

How do I change the data directory to my preferred location?

TIA
Jim
