PJB 100 USB driver for Vista - where to get?

[Ernst Erb]

I try (after many years) to get my PJB 100 connected to my PC with Vista, but I can not find an USB driver.

On my old CD there is a file
cpqpjb.sys
the system searches in the folder
C: Windows/twain_32 for a driver - so I have dropped it there - but the driver can not be found.

Can somebody tell me what to do or where to find the proper (or a working) driver please?

Cordially,
