Download and install the free version.

Under the Edit menu choose Preference / Registration.

Installing Quicktime Pro for Windows

I followed your outline. Thanks. I will now see if I did it correctly. It did again ask me to purchase it, I didn't click that but hit OK and it went away. So, we will find out. At least you got me to that point.
