Thanks to all!
Turns out I have both. The desktop icon opened the 32 bit but I started the 64 bit from its .exe and it runs, verified it with a look at the Help/About. I placed an icon on my taskbar for both.
I've been trying the Firefox Nightly 64 bit, but it is buggy and slow. Not unexpected in a developing version. Mostly I use Chrome and Firefox (32). Today on a whim I clicked the IE9 icon and was pleasantly surprised at the speed and overall appearance. I must be months since I opened it. So then, the thought process, 'how about the 64 bit version?' Just now I opened a couple of sites with 64 and it looks good and is quick.
Thanks again for all the responses.
