I have noticed several references to FSUIPC in my research but still have no idea what it is or how to get it.

My interest was piqued when I noticed that many products require FSUIPC in order to run properly. I also noticed that FSUIPC comes registered and unregistered. What is the difference?

In particular, I was just reading a review in Computer Pilot Magazine from Feb. 2007 of Aerosoft's Flight Calculator Version 2. The review said that the program requires FSUIPC, registered of unregistered, to run, in MSFS. The calculator works in FSX or FS9 so I'm assuming FSUIPC is something suitable to both versions of FS.

So, once again: What is FSUIPC? What does it do? And, how do I get and install it?
