32bit & 64bit sonar's global options

Hi all
I have both 32bit and 64bit versions of sonar 8.5 installed and I have created two project folders for each version but for some reason they seem like Siamese twins and insist on sharing the same folders.
So if I open up sonar 8.5 32bit and change my default project folder to the 32bit one that I created, 
I will find that Sonar 8.5 64bit has changed it's default folder too which is not what I want.

I think I made the mistake of migrating project settings when I installed them but is there away of separating them without having to uninstall and re-install again?

Cheers

Steve

That's what I had to do Cactus, or at least 8.3.4
It would be good if the installer gave you a list of options as to what you would like sonar to share, things like sound card settings and vst folders are a given but not project and audio folders (if like me you still use a global audio folder and not per project.
