QTR-Quadtone RIP

I want to create some curves for the 3880 on Windows XP, which presents 
a problem:
QTR 2.6 doesn't support the 3880
QTR 2.7 is broken on the PC for curve generation

I've searched through the list messages and there are instructions for 
using QTR 2.6 with the 3880 on Macs (by making it appear to be a 3800), 
but not for PCs.

can anyone advise how to get the 3880 to appear to be a 3800 for QTR 2.6 
on a PC running Windows XP, please (or failing that on Windows 7, though 
I don't really want to upgrade at present)

Thanks,
mike
