Hi Matthew,
The only drivers I have installed prior to the Avid installation are the ones required by the Nvidia Quadro FX1500 graphics card.
There is no hardware attached (e.g. digidesign pro-tools mbox, external video/audio input output hardware etc) that might interfere with the installation.
I have also carried out the routine XP optimizations stipulated in the Avid optimization for XP pdf document.
The install will still not proceed past the installation of the digidesign drivers.
Many thanks for any advice, Tom.
