When I open PI 10 in Vista Home Premium - I get a little message that says "can't update registry - try going to regedit". Now, what does that mean?

However, PI 10 continues to load.

I can load the presets in PI 10 but, you have to let them fall where they may. The presets do work so far.

I re-opened PI 10 this morning and the presets are still there so, just MAYBE!!

Any suggestions as to what "can't update registry - try going to regedit" means - and how to go about fixing this?
