Making RealPlayer function with Vista 64-bit

Let me be more precise. I was a little frustrated. I have Windows Vista
Ultimate 64-bit. I have plenty of PC to run it. 3GB memory, dual core
processor, bla, bla, bla. Since I installed it, I have not been able to get
RealPlayer to function. I had the regular 32-bit version of XP. The player
worked fine then. I did not know in advance that the 64-bit OS would be this
much of a problem with some things. I am not even able to activate my
computer with them. Thus far they have not come up with a solution. But who
says they are the sharpest tool in the shed? I was wondering if anyone else
out there has had a similar experience and if they found a way to work it
out. I wish I was as smart as most of you all out there but... I am not
particularly in love with them, but I am in love with the music. Any
suggestions?
