On the Vista 64 bit and 32 bit comps I have now transferred the PGMUSIC folder to the computer as indicated in the PG disc instructions and your comments. B&B works OK now with Realtracks and Realdrums. I was still getting a warning in B&B that the MS wavetable was being used by another program.!? When hitting Play. (on both Vista comps).

So first on the Vista 64 bit comp I went to the vsc install folder (c:/bb/vsc/vsc_installs ) and ran VSC-Dxi_setup program. It initially gives an error but Vista comes back with the option of setting with new settings. Clicking this option it loaded OK.
Now in the MIDI driver menu in B&B I then set the sound card as - Roland VSC-Dxi - without ticking the - Use VSC-Dxi synth - and low and behold the message no longer appears and I am getting the B&B instruments to play OK !!.

So the Vista 64 bit comp is now up and running. Great.

On the Vista 32 bit when I run the VSC-Dxi_setup program I do not get the initial error message and it loads OK. Following the same procedure above and it yields the same results.

Cheers. FK
