QTR-Quadtone RIP

Are there any tricks to initiating this prgram other than to double 
click on it in the Eye-One folder. I am trying to do it that way and I 
get an error message saying that it cannot create a temp file in the 
default users pdk directory. Anyone come across this before?

My other question is whether QTR is due for release on Vista anytime 
soon. I was going to upgrade to a more powerful PC running Vista but 
QTR only seems to support XP and 2000.
